Re: [regrep-comment] Request: Cataloguing for ExternalLinks

[Farrukh Najmi <farrukh.najmi@sun.com>]

Steve,

This is an excellent suggestion and one that has been reviewed by the 
ebXMl Registry TC. In light of your suggestion we will generalize the 
content cataloging mechanism such that content referenced by external 
links may also be catalogued as you suggested. The details will be 
available in the next version of the RIM and RS specifications.

Thanks for this useful suggestion.
