* 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.

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