msxml3: Revert: msxml3: Reuse MXAttributes implementation for SAX reader attributes reporting.

This reverts commit c2c8b9e771 and adds
a comment for uri reporting feature that some application use, for
example Office 2010.  The problem is that namespace uri pointer should
stay the same and we keep it in element stack for that, MXAttributes
allocates new string for each attribute and won't work as needed
unfortunately.
