Hi,
I just inherited a project after somebody leaving the company I work for. Part of the project are a number of stylesheets to format raw XML for rendering them in a browser. This all seems to work pretty well, but I'm confused about the fact that 2 (identical

) copies of every stylesheet are present:
<stylesheet>.xsl
<stylesheet>.xsl.xml
I'm very new to XSL, and tried searching the web in various ways, but to no avail (the search phrases I can come up with don't work very well in search engines).
Does anyone know of any reason to do this? Or is this some left-over from an old issue that has long been solved? Or should I just simply delete the "xsl.xml" files?
Thanks beforehand for any assistance,
Juul
