Chirstian,

I'm also starting to a few DITA projects with BaseX that use attributes for matches. Other projects were DITA-like and did not need to match attribute tokens in @class. There is a big and growing DITA community out there who need native XML database support, I think it might be interesting to include indexing attribute tokens in the roadmap at some point, even if only as a longer term items.

This is a very important aspect of the DITA standard. HTML classes also use tokens

more and more. So that's not just relevant to the DITA community.

Regards,

France

I took this use case to the XQuery & XSLT Working Groups a year or two
ago (Jirka added the DITA case - I was thinking of (X)HTML) and the
result was contains-token() which might be easier for the database to
optimize.

Judging by comments submitted against my awful tests for it :) I think
BaseX may well support it already.
