Hi Probal,

Sorry not to have answered more promptly.

The 'www-xml-linking-comments' mailing list is for sending in
comments on the XML Linking and Pointer specifications. Comments
tend to accumulate and be handled in batches. You may have
better luck in getting a quicker answer to your question if you
ask it on the xml-dev mailing list (xml-dev@lists.xml.org).

Having said that, yes, there are limits on the nesting
of elements using the xlink attributes. Basically, you
can't nest links. (To be more precise, nothing prevents
you from nesting them, but the nested elements do not
have any XLink meaning, so why bother?).

There are some ways of working around this by using
external links whose originating resources overlap, but you
are still faced with the basic question of what destination
does the user want when a link is nested? If you only
give them one choice, then why bother with a nested link?
If they are given multiple choices, how are they to indicate
their choice?

If you have a real need for nested links, the group would
be interested in seeing it.

Best regards,
