Key and Color Coding

In the following tables, three colours are used to denote standard classifications of the rows:

  • Light Blue - the class definition;
  • Grey - a standard feature;
  • Indigo - an extension feature.

The key to the columns used in the following profile comparison details is:

  • Identifier - a unique identifier for the element/attribute in this table (indentation reflects any hierarchy due to abstract classes). All attributes are labeled using alphabetic characters;
  • Element/Attribute Name - the name of the element/attribute (an attribute is shown with the first character of @). All colon delimited names are defined in an external imported XSD. If the entry "Abstract" is used then this denotes that the model included an abstract class (the content of this class are explicity defined at this point in the list);
  • Multiplicity - the permitted multiplicity defined as a [lower .. upper] value (* denotes the upper limit is unbounded and a value of [1] means a single required instance);
  • Data Type - the named data-type of the element/attribute. The annotations mean:-
    • PT:{data-type} - a primitive data type mapped to XML data-type
    • DT:{name} - a derived data type mapped to the parent type
    • Enumeration - an enumerated set of permitted values
    • Sequence - a sequence complexType
    • Selection - a choice complexType
    • Any - an any complexType
    • Unordered - a constrained choice complexType
    • Mixed - the complexType can contain a mixture of text and elements (this value accompanies either Sequence, Selection, Any or Unordered)
    • List - a list of values
    • EnumeratedList - a list of values selected from an enumerated set of values
    • Union - a value that is a union of one other primitive data-types
    • Import - an element that is sourced from an external XSD.

Derived Data-Type Checklists

This is the definition of the set of derived data-types used in this specification and its associated profiles. In the cases where the named child elements are "pattern", "whiteSpace", "minLength", "minInclusive", "maxInclusive" or "maxLength" then these are used to constrain the value of the parent and will not occur as child elements in an instance.

Class Attachment.Type - N/A - PT:Empty - N/A -
a
->@href [1] PT:AnyURI -

Primitive Data-Type Definitions

This is the definition of the set of primitive data-types used in this specification and its associated profiles.

Data-type Name Description
AnyURI This is mapped to the XML "xs:anyURI" data-type.
Boolean This is mapped to the XML "xs:boolean" data-type.
Empty This is used to denote an element that will not contain a value i.e. it is empty.
Float This is mapped to the XML "xs:float" data-type.
ID This is mapped to the XML "xs:ID" data-type.
Namespace This provides a strict namespace-based extension facility.
String This is mapped to the XML "xs:string" data-type.
