keythe identifier used for the required class within the source indicated.
Status Required
Datatype teidata.xmlName
expandindicates how references to this class within a content model should be interpreted.
Status Optional
Legal values are:
alternate
any one member of the class may appear
sequence
a single occurrence of all members of the class may appear in sequence
sequenceOptional
a single occurrence of one or more members of the class may appear in sequence
sequenceOptionalRepeatable
one or more occurrences of one or more members of the class may appear in sequence.
sequenceRepeatable
one or more occurrences of all members of the class may appear in sequence
Note

If the members of the class are a, b and c, then a reference to the class within a content model is understood as being a reference to a|b|c when expand has the value alternation; to a,b,c when it has the value sequence; to (a?,b?,c?) when it has the value sequenceOptional; to (a*,b*, c*) when it has the value sequenceOptionalRepeatable; or to (a+,b+,c+) when it has the value sequenceRepeatable.
