Updated testsuite schema

Folks,

I updated the test suite schema today. I added a new attribute
ignore-whitespace-differences to the t:test element.

If explicitly set to "true", the test results should be compared
without regard to the placement of whitespace in the document. This
makes the test documents for things like p:delete much less "fiddly".

If the attribute is absent, or explicitly set to "false", then the
comparison should respect any whitespace in the documents.

                                        Be seeing you,
                                          norm
