I added functionality to
org/apache/xerces/validators/datatype/StringValidator.java to let Schemas
validate enumeration/literals and
maxLength in datatypes based on 'string'.
Example:
<datatype name='newtype'>
<basetype name='string'>
<enumeration>
<literal>AAA</literal>
<literal>BBB</literal>
</enumeration>
</datatype>
I realize that this is already obsolete syntax based on the 12/17 Schema draft
but I needed it and thought others may. The diff is
below.
