Many thanks Wendell for your comprehensive explanation.  Events
somehow conspired to convince me that call-template behaved
differently to apply-templates, and that I didn't need to explicitly
pass parameters from the caller, nor declare them in the callee.

As I wrote the stylesheet (based on this assumption), each new
addition of conditional logic seemed to work, nay, _did_ work, as I
intended, further convincing me of my incorrect understanding!

Anyhow, the stylesheet is now about 20 lines longer due to the
addition of lines like this in the callers:

(1) <xsl:with-param name="name"><xsl:value-of select="$name" /></xsl:with-param>

It was probably also the seemingly pointless and repetitive nature of
this mechanism that served to further convince me that "this can't be
necessary!"  I can see why 'tunnel parameters' have been introduced,
if they serve to cut down on the number of lines like these,
especially (1).

Cheers,
Wendell
