That's all true, Trevor.

Possibly we don't think of this since xsl:apply-imports is rare enough we're not tuned into it as being effectively an inheritance mechanism (and useful as such).

On the other hand, maybe now we will be.

Yet it's typical of XSL-List that we've seen four decent solutions to this problem already today (conditional logic, modes, matching the attribute, and using xsl:apply-imports), and learned something while we were at it.

This is really a very old pattern but in a new context.  In
object-oriented languages it is common to write a class which inherits
from another, overrides a method (or two), do some new stuff, then
call the base version of the same method to do what the base class

Which is why I've been kicking myself for not thinking of the
apply-imports method first - I've been using OOPLs a lot of years, and
well know the correspondence between XSLT import and inheritance.  Oh

The interesting thing XSLT has over OOPLs in general is that since the
method name is essentially the template match pattern you get to
overide many "methods" (templates) at once, as in the *[@mark] trick.
A new feature for Java 3 maybe...
