My apologies for not clarifying this on the include-pattern page - I could
have swore I had done so, and it was one of these core aspects of its design
that I'm quite surprised did not make it to the wiki.
The short answer is no, the include-pattern DOES NOT support data outside
the current page.
I've added a section:
As well as added it as an FAQ item (as I think I have heard this question
before, and certainly want to make it clear).

I think the dependency of that kind of context from a separate page is poor
information design, but that might not be something you can change.
The page itself must contain sufficient information for the microformat. It
can be a minimal version that points to another page for more details.

No it is not good. People print out pages. Pages get moved. Pages get
copied and pasted, and the first things to break are such cross-page
content/context dependencies. Relying on data on another page introduces a
significant amount of fragility.

Thanks for the heads up - again, apologies for not documenting this in the
