Thank you for the info.
I also had to:
- prefix the "refer"-values in the keyref definitions
- prefix the references to the "description" elements
and then it worked.

Hi Guy,
The default namespace does not apply to XPath expressions, so you must use
prefixes for names which have a namespace. The following should work:
<xs:element xmlns:a="http://www.fks.be/fsm"; ...>
...
<xs:key name="state-name-pk">
<xs:selector xpath="./a:state"/>
<xs:field xpath="@name"/>
</xs:key>
<xs:keyref name="sn1" refer="state-name-pk">
<xs:selector xpath="./a:transition"/>
<xs:field xpath="@from"/>
</xs:keyref>
<xs:keyref name="sn2" refer="state-name-pk">
<xs:selector xpath="./a:transition"/>
<xs:field xpath="@to"/>
</xs:keyref>
<xs:keyref name="sn3" refer="state-name-pk">
<xs:selector xpath="."/>
<xs:field xpath="@start"/>
</xs:keyref>
</xs:element>
Thanks.

Can anybody tell me why I get the error message shown in the Subject
when running the sample Count program as follows?
I am trying to validate an xml instance against a schema.
java -classpath xercesSamples.jar:xercesImpl.jar:xml-apis.jar
dom.Counter -v -s fsm.xml
The xml and xsd files are listed below.
Thank you
PS. I also tried specifying 1.1 in the xml processing instruction, both
in the xml and xsd, but then I get:
"XML version "1.1" is not supported, only XML 1.0 is supported."
