RE: [xsl] Cannot have an attribute node (style) whose parent is a document node

Using xml:space="preserve" in a stylesheet generally isn't a good idea. In
this case I think it has led to you outputting a whitespace text node child
of an element before producing an attribute of that element. And then you've
been caught by a poor error message - which might be fixed if you moved to a
more recent release, as it's a known problem area.

In XSLT 1.0 this was a recoverable error and the processor was allowed to
recover by simply ignoring the offending attribute. The error was changed in
XSLT 2.0 to be non-recoverable, which might account for the difference
between processors.

Hello everyone, and thanks in advance for the help. I'm doing 
some pretty simple(I thought) xslt processing and I've come 
across an error I cannot figure out. I'm using Saxon 9.0.0.2 
through Stylus studio.

Saxon Error:

When I run it through the Stylus Built-in processor I get the 
output I expect:

              <p

Session, 38th Parliament</p> </root>

Any thoughts would be appreciated.

Thanks,
