April 5, 2000: From uidesign.net, a proposal to the W3C: XML Document Navigation Language outlines a syntax for marking up data for navigation within a document (for teeny-tiny screens like cellphones and butter dishes). As the uidesign review of XDNL points out, this may work for static documents, but not as well for applications. (I also think we probably ought to avoid designing all our content-delivery tools for the crappy displays on today's cellphones).

I think a big part of the trouble is that we're trying to organize all types of data (including applications) in terms of documents. It's that same old the-web-was-designed-for-physics-papers problem.
