But if a document is statically known, it is potentially available using the doc() function, hence I think the use of doc-available() in use-when should be legal, although if it isn't it isn't.

You are quoting the XPath spec here, which allows enough breath for host
languages to provide a list of statically available documents. However,
in the section that you also refered to,
http://www.w3.org/TR/xslt20/#conditional-inclusion, you should scroll
down until the bottom of the first table, there is says:

Statically known documents     None
Statically known collections     None

which may be a bit of an unpleasant surprise, which is why this was
relaxed in the XSLT 3.0 specification, as Michael Kay mentioned in his
previous reply.

If you have the ability to use an XSLT 3.0 processor, you may be able to
use this feature.
