Xerces bug: xcatalog problems

[Mark Diekhans]

With Xerces 1.0.2 using XCatalog, a mapping of a SystemId one fails due to
XMLParser.startReadingFromExternalEntity calling fReaderFactory.createReader
with the old system id instead of the mapped one.

enclosed:
    stack - Stack trace showing the resulting error.
    patch - Patch that made it work (but I am not convinced its correct)
    index.wml - Document 
    wml.xcat - XCatalog file
    wml_1.1.xml - DTD we are after.

Using JDK 1.2.2

Thanks,
Mark
