But we don't mean, for apply-templates, any specific template; we mean
"take this sequence of nodes and figure out which template should
apply, just as in xsl:apply-templates", so we have to handle mode and
priority.

It could be fn:perform-template-matching($nodeSet,$mode,$priority) and
it wouldn't work in XQuery.

Similarily it could be fn:apply-named-template($templateName,$contextItem) and it still wouldn't work in XQuery.

There is no obvious reason -- other than the effort and sanity of the
implemetors -- there couldn't be a template-function derivative of the
base function type, and those have the mode component of the arity.  But
that is not so much a feature as a new language that goes
one-ring-to-rule-them-all on XPath, XQuery, and XSLT.
