That's equivalent, it's conceptually clearer if people are comfortable
with slash-sequence, but I'm not sure it's clearer as a syntactical
expression.

I think I mostly want something like

div[only(heading,para)]

but that raises the question of what only() would do with comments and
processing instructions.

(And yes, I could perfectly well write a local:only().)
