1. Introduction

1.1. Scope and Context

This QTI HTML5 v2.2 specification is an extension to the core IMS QTI ASI specification and enables support for a number of HTML5 tags. The QTI Information Model is bound to an XML Schema Definition (XSD). This document and the accompanying XSD is generated using the IMS Binding Auto-generation Tool-kit (I-BAT) [I-BAT, 06].

1.2. Conventions

All sections marked as non-normative, all authoring guidelines, diagrams (with the exception of the UML diagrams), examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119]. This means that from the perspective of conformance:

The Conformance and Certification Guide for this specification may introduce greater normative constraints than those defined here for specific service or implementation categories.

The SHOULD/SHOULD NOT/RECOMMENDED statements MUST NOT be used in any document, or section of a document, that is responsible for defining the information model and/or the associated bindings and/or conformance and certification.

Characteristics	The set of directly inherited characteristics are: id language title label class dir role aria-controls aria-describedby aria-flowto aria-label aria-labelledby aria-level aria-live aria-orientation aria-owns aria-hidden dataExtension
Children	The set of children attributes are: flowGroup
Description	This defines the permitted content for the HTML5 'article' tag. The article tag represents a complete, or self-contained, composition in a document, page, application, or site and that is, in principle, independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content. When article tags are nested, the inner article tags represent articles that are in principle related to the contents of the outer article. For instance, a blog entry on a site that accepts user-submitted comments could represent the comments as article elements nested within the article tag for the blog entry. Author information associated with an article tag (q.v. the address tag) does not apply to nested article tags.

Descriptor	Definition
Characteristic Name	aria-flowto
Data Type	IDREFS (Primitive-type)
Value Space	See Appendix A1.3.
Scope	Global ("+")
Multiplicity	[0..1]
Description	This is a part of the ARIA annotation. Identifies the next tag (or tags) in an alternate reading order of content which, at the user's discretion, allows assistive technology to override the general default of reading in document source order.

Descriptor	Definition
Characteristic Name	aria-label
Data Type	NormalizedString (Primitive-type)
Value Space	See Appendix A1.3.
Scope	Global ("+")
Multiplicity	[0..1]
Description	This is a part of the ARIA annotation. Defines a string value that labels the current tag. See related aria-labelledby. The purpose of aria-label is the same as that of aria-labelledby. It provides the user with a recognizable name of the object.

Descriptor	Definition
Characteristic Name	aria-labelledby
Data Type	IDREFS (Primitive-type)
Value Space	See Appendix A1.3.
Scope	Global ("+")
Multiplicity	[0..1]
Description	This is a part of the ARIA annotation. Identifies the tag (or tags) that labels the current element. See related aria-label and aria-describedby. The purpose of aria-labelledby is the same as that of aria-label. It provides the user with a recognizable name of the object. The most common accessibility API mapping for a label is the accessible name property. If the label text is visible on screen, authors SHOULD use aria-labelledby and SHOULD NOT use aria-label. Use aria-label only if the interface is such that it is not possible to have a visible label on the screen. As required by the text alternative computation, user agents give precedence to aria-labelledby over aria-label when computing the accessible name property. The aria-labelledby attribute is similar to aria-describedby in that both reference other elements to calculate a text alternative, but a label should be concise, where a description is intended to provide more verbose information.

Descriptor	Definition
Characteristic Name	aria-level
Data Type	AriaLevelInteger
Value Space	Container [ DerivedType ]
Scope	Global ("+")
Multiplicity	[0..1]
Description	This is a part of the ARIA annotation. Defines the hierarchical level of an tag within a structure. This can be applied inside trees to tree items, to headings inside a document, to nested grids, nested tablists and to other structural items that may appear inside a container or participate in an ownership hierarchy. The value for aria-level is an integer greater than or equal to 1.

Descriptor	Definition
Characteristic Name	aria-live
Data Type	ARIALiveValue
Value Space	Enumerated value set of: { off \| polite \| assertive } Default = "off".
Scope	Global ("+")
Multiplicity	[0..1]
Description	This is a part of the ARIA annotation. Indicates that a tag will be updated, and describes the types of updates the user agents, assistive technologies, and user can expect from the live region. The values of this attribute are expressed in degrees of importance. When regions are specified as polite, assistive technologies will notify users of updates but generally do not interrupt the current task, and updates take low priority. When regions are specified as assertive, assistive technologies will immediately notify the user, and could potentially clear the speech queue of previous updates.

Descriptor	Definition
Characteristic Name	aria-orientation
Data Type	ARIAOrientationValue
Value Space	Enumerated value set of: { vertical \| horizontal } Default = "horizontal".
Scope	Global ("+")
Multiplicity	[0..1]
Description	This is a part of the ARIA annotation. Indicates whether the tag and orientation is horizontal or vertical.

Descriptor	Definition
Characteristic Name	aria-owns
Data Type	IDREFS (Primitive-type)
Value Space	See Appendix A1.3.
Scope	Global ("+")
Multiplicity	[0..1]
Description	This is a part of the ARIA annotation. See related aria-controls. The value of the aria-owns attribute is a space-separated list of IDREFS that reference one or more elements in the document by ID.

Descriptor	Definition
Characteristic Name	aria-hidden
Data Type	Boolean (Primitive-type)
Value Space	See Appendix A1.3. Default = "false".
Scope	Global ("+")
Multiplicity	[0..1]
Description	This is a part of the ARIA annotation. It indicates whether the element is exposed to an accessibility API.
