Description Frank Gross 2007-07-11 16:07:36 UTC 
Validation of XML documents with a XML Schema containing IDCs and importing other XML schemas with IDC inside, generates an internal error.

See attached test case that produces following output:

$  xmllint --schema MainSchema.xsd Main.xml

Main.xml:4: element AnotherElement: Schemas validity error : Internal error: xmlSchemaIDCRegisterMatchers, Could not find an augmented IDC item for an IDC definition.
Main.xml:4: element AnotherElement: Schemas validity error : Internal error: xmlSchemaValidateElem, calling xmlSchemaValidateElemDecl().
Main.xml:4: element AnotherElement: Schemas validity error : Internal error: xmlSchemaDocWalk, calling xmlSchemaValidateElem().
Main.xml validation generated an internal error

And take a look at proposed patch.

Okay, the patch looks sane, and seems to fix the problem, and doesn't
introduce any detectable regressions. So I applied it added the test to
the regression suite and commited it to SVN, 

   thanks a lot !
