This post is for posterity.
I have found that using:
XSLTAddFilter cgi-script
has the desired effect, despite "cgi-script" not being defined as a
mime type anywhere in any files I can find that are being consulted by
Apache.
For the record, I am using Apache 1.3.33 and mod-xslt 1.3.8
Hopefully other people with the same trouble I was having will stumble
upon this in the archives.
I also have the following in my httpd.conf:
<Directory />
Options FollowSymLinks ExecCGI +Includes
AllowOverride All
# Addhandler mod-xslt .xml
XSLTTmpDir /tmp
XSLTEngine ON
XSLTAddForce application/x-httpd-cgi
</Directory>
When uncommented, the Addhandler line functions properly - however the
dynamic processing never seems to kick in.
Any assistance in this would be greatly appreciated.
Thank you,
