I have adopted this rule (Maps before Delegates) in my 0.2 draft
at http://www.ccil.org/~cowan/XML/XCatalog.html .

Indeed.  I now define it as an optional feature of XCatalogs: a
conformant processor need not do Remaps.

Quite right.  However, if the "htmlcatalog" file does not help you,
you do *not* get returned to the original catalog or its successors
(via Catalog entries) to search further. Once delegated, always
delegated.
 
Please read my new draft and let me know what you think.
