RE: how to include an ampersand in an html href using xt and xsl?

["John Sidlo" <jsidlo@xxxxxxxxxxxxx>]

Eric, thanks for your response. You've confirmed my suspicions/fears.

To the XSL community:
In my opinion this is a flaw in the xslt specification. Most (all?)
existing servers use the ampersand in query string to separate
parameters, and the xslt spec expressly forbids generating an ampersand
in an attribute (see section 16.4 of XSL Transformations).  While it is
fine for the xslt specification to by default require HTML 4.0
conformance, I believe it should allow 'disable-output-escaping="yes"'
within an attribute, especially when so many servers and CGI
implementations require it.

It seems to me the only choice I have is to post-process the html output
string to generate href's with ampersand!

I hasten to add that if I'm wrong about this, I'd love to be corrected
(even chastised)!
