Re: problem with namespace="" in sx2ml stylesheets

Hi Marc-Olivier,

thanks for pointing this out. I have taken a look into the XSLT spec and 
you are certainly right, a zero length string is not an URI at all, 
which is allowed as value of the namespace attribute.
This was earlier meant as a work-around for namespace problems for the 
access of elements in variables using a different XSLT processor.
Nevertheless, the current version works fine with Apache Xalan, which is 
being shipped together with OpenOffice / StarOffice to assure a 
consistent behavior of the transformation even with JDK 1.3 and 1.5.
Therefore and due to my current commitment on other parts of OOo, I 
believe the fix will come in a little later.
Could you please write me ('SUS') an issue with the target "OOo 2.0.1". 
Simply paste your letter as issue description.

Thanks in advance,
Svante
