ID values used for linking and must be uniq, right?

In modular set of docbook/xml after processing XInclude some
documents may to have duplicates of ID. 

I think what using 
'xml:base' + 'filename' + 'id'
can produce uniq values as result. In this case final
value of 'xml:base' can be calculated also from 'xml:base' of
parent tags (if there exists relative values).

This changes appear 'idref' of <xref/> and <link/>.

For images we have a similar problem - files with images must
have uniq names.

BTW, all html build exist in the one dir (except <sitemap>
of olinking schema from Bab Stayton). 'xml:base' could be useful
for split documents into separate dirs.

Sorry for disturb.
