Why would the
the processor have to think up prefixes on the fly?
Well firstly it may always do that even if it doesn't have to, as the
namespace rec sort of half implied that a xml+namespace parser needn't
preserve the namespace prefixes, so XSLT does not assume that they are
preserved, it can work with an xml parser that just returns names as
uri+localname and more or less everything works almost nothing in xslt
assumes anything about the prefixes used in the source document.
The only constructs that access the prefixes are name() and the
namespace:: axis, and in both cases the system is explictly allowed to
use any consistent prefix it wants, it doesn't have to use the one in
the source.
that said, most systems do try to preserve prefixes as people get cross
(as seen on a thread on this list last week) if you start with <html
xmlns="http://www.w3.org/1999/xhtml> and the system produces names like
<_lakjsgawkebrc23o7qiu:html
xmlns:_lakjsgawkebrc23o7qiu="http://www.w3.org/1999/xhtml";>
Wouldnt the association of
namespace prefix to urn for any namespaces being used have to occur in
the stylesheet
namespace declarations in the stylesheet (most likely) have no effect on
the prefixes used by name() most systems try to preserve prefixes from
the source.
