[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Random Namespaces Declared with XSLT Stylesheet... why
 I've been hacking a quick-and-dirty transform for turning a custom
language [1] into HTML (for presentation), but I've got some odd
behavior. The stylesheet seems to randomly put namespace declarations
where they're not needed. Why is it doing this?
Note:
* I'm using Xalan-J for transforms.
* The stylesheet can be found at [2].
* The input document can be found at [3].
* The output document can be found at [4].
Oddly, the stylesheet works in Internet Explorer 6 (with msxml.net
installed) but not in Mozilla (version 1.4b tested). The Stylesheet is
also transcribed (with tabs converted into double-spaces for the
fixed-length nature of the email) at the end of this email, but I still
have the links posted [5].
