Validity constraints for attribute values syntax are checked in xmlValidateAttributeValue

[ VC: ID ] Values of type ID must match the Name production. A name must not appear more than once in an XML document as a value of this type; i.e., ID values must uniquely identify the elements which bear them.

[ VC: One ID per Element Type ] No element type may have more than one ID attribute specified.

[ VC: ID Attribute Default ] An ID attribute must have a declared default of #IMPLIED or #REQUIRED.

    [10] AttValue ::= '"' ([^<&"] | Reference)* '"' |
                      "'" ([^<&'] | Reference)* "'"

3.3.3 Attribute-Value Normalization:

Before the value of an attribute is passed to the application or checked for validity, the XML processor must normalize it as follows:

- a character reference is processed by appending the referenced character to the attribute value
- an entity reference is processed by recursively processing the replacement text of the entity
- a whitespace character (#x20, #xD, #xA, #x9) is processed by appending #x20 to the normalized value, except that only a single #x20 is appended for a "#xD#xA" sequence that is part of an external parsed entity or the literal entity value of an internal parsed entity
- other characters are processed by appending them to the normalized value

If the declared value is not CDATA, then the XML processor must further process the normalized attribute value by discarding any leading and trailing space (#x20) characters, and by replacing sequences of space (#x20) characters by a single space (#x20) character. All attributes for which no declaration has been read should be treated by a non-validating parser as if declared CDATA.

Parameters

  ctxt | an XML parser context

Returns
  the AttValue parsed or NULL. The value has to be freed by the caller.
