In what sense are you using the word "document"?

If you mean "data sources that don't have mixed content", you might be
right. But if you mean data sources with mixed content (and, yes,
people want to combine and restructure that too sometimes) I think
you're entirely wrong about the pull model. Actually, I think the pull
model is way overused even in the data case, but that may largely be a
matter of style as either will suffice in that case.
