RE: [xsl] Is it possible to test if a named template exists?

["Michael Kay" <mike@xxxxxxxxxxxx>]

Provided you use import rather than include, you could define a template
with the required name in your (imported) module: when you call it, if your
local version is called then you know there wasn't one with that name in the
importing module.

Has to be "import", because otherwise it's an error to have two templates
with the same name.
