global cross file refs

global cross file refs

[Hans Hagen]

Hi, 

As you may know, cross file refs can be resolved in two ways: 

\usereferences[somefile]

\useexternaldocument[somefile]

where in the first case no cross file refs are possible but only the labels
etc show up, while in the second case (the official one) the refs are
accessible as \in {...} [somefile::ref] and result on cross file hyperlinks. 

the next release will have an option \setupreferencing[global=yes] which
permits you to omit the somefile:: prefix, but of course at the cost of
conflicting refs in multiple loaded files. Nevertheless, sometimes this
feature canbe handy.

Local and prefixed things have a higher priority anyway. I will implement a
more advanced prefix mechanism [nested] some day soon, since in etex the
penalty is not that high as in normal tex. Btw, if you say
\setuphead[chapter][prefix=+] you get auto prefixing, and when you say
\chapter[someref]{...} the someref becomes the prefix, which can safe you
some troubles.

That's good enough.
