[jira] Created: (XERCESC-1896) Bogus diagnostics when an unknown name is referenced from imported namespace

Bogus diagnostics when an unknown name is referenced from imported namespace
----------------------------------------------------------------------------

                 Key: XERCESC-1896
                 URL: https://issues.apache.org/jira/browse/XERCESC-1896
             Project: Xerces-C++
          Issue Type: Bug
          Components: Validating Parser (XML Schema)
    Affects Versions: 3.0.1
            Reporter: Boris Kolpackov
             Fix For: 3.1.0
         Attachments: test.xml, test.xsd

Run DOMCount on the attached test case like this:

DOMCount -v=always -n -s -f test.xml

You will get the following error messages:

Error at file /tmp/test.xsd, line 7, char 47
  Message: namespace 'http://www.w3.org/2001/XMLSchema' is referenced without import declaration

Error at file /tmp/test.xsd, line 7, char 47
  Message: namespace 'http://www.w3.org/2001/XMLSchema' is referenced without import declaration

Error at file /tmp/test.xsd, line 11, char 37
  Message: base type 't:isbn' not found in 'isbn2' definition

There are two problems. The first is the bogus message in the first two errors. The second is the two duplicate error messages. The second problem disappears if we remove isbn2 type from the schema.

Boris Kolpackov closed XERCESC-1896.
------------------------------------

    Resolution: Fixed
      Assignee: Boris Kolpackov

Fix for the first issue is in SVN. The second issue is due to the (misguided, IMO) recovery logic in Xerces-C++.
