XML Schema validation - xml:base attribute

The Xinclude faq (http://xml.apache.org/xerces2-j/faq-xinclude.html)
says to allow xml:base attributes to appear on elements that might be
included from different base URIs.

I've tried and get the following error when I run `java sax.Counter -s
entity-inc.xml' (note that entity-inc.xml has been pre-processed with
XIncluder)

[Error] entity.xsd:28:52: s4s-att-invalid-value: Invalid attribute
value for 'name' in element 'attribute'. Recorded reason:
cvc-datatype-valid.1.2.1: 'xml:base' is not a valid value for
'NCName'.

Why is 'xml:base' an invalid name for an attribute?


My xml:base attribute in entity.xsd is

  <xs:attribute name="xml:base" type="xs:anyURI" />


Thanks.

Apparently the parser's complaining about your schema, not your instance.

Did you have something like:

<attribute name="xml:base" ...>

This is not allowed. The value for "name" has to be an NCName, which means 
"no colon name".

You may want to import the "xml" xsd and use an attribute reference:

<attribute ref="xml:base" ...>
