Hi,
I'm interested in doing a profile of the XML
Signatures schema. I.e. I want do do a restriction of the XML Signature
schema.
However while doing this I have bumbed into a few
problems.
At first I got an error saying:
[Error] General Schema Error: Grammar with uri: http://www.w3.org/2001/XMLSchema
, can not be found; schema namespace may be wrong: Xerces supports schemas fro m the "http://www.w3.org/2001/XMLSchema" namespace or the instance document's na mespace may not match the targetNamespace of the schema. I found some info about this and solved this
problem by adding the following to my schema:
<!DOCTYPE xsd:schema [
<!ENTITY % schemaAttrs 'xsi:schemaLocation CDATA #IMPLIED xmlns:xsi CDATA #IMPLIED'> ]> This enables me to point to where the XMLSchema is
at. Now I bump into another problem that I have not solved yet, and I'm not sure
what causes it.
[Error] test.xsd:13:44 Schema error: prefix :
[xml] cannot be resolved to a URI
Below is my schema, any suggestions?
Thanks,
/Peter
