Bruce,

In effect what you're learning is that as you apply templates to one or another node, you sometimes have to "carry your context with you". You are doing this with parameters.

So if your calling a new template switches the context back to the $cite-ref, pass the db:citation context as a parameter as you do so. Then in the cite-ref context, assuming the db:citation is bound to $citation, your test would look like

count($citation/../db:citation) = 1 and
$citation/@linkend = $citation/preceding::db:citation[1]/@linkend

(See those location paths start from a node bound to a parameter, instead of implicitly from the current node, which has switched.)

This switching back and forth (and the resulting question, "which tree am I on?", which fortunately isn't generally hard to answer) is of the essence of the kind of solution you are designing; once you get the hang of it it's kind of fun.

Cheers,
Wendell

Of course you'll have to fix the typo. (I must be channeling DC. ;-)
Got it. But what if I need to use this is another template, where I again have to switch context to the $cite-ref parameter (as element())? Am not sure how to do that with the preceding axis bit.
