Markup: Bulletproof XHTML: Good points here on the practicality of pure XHTML.
“It’s easy to do a one-off conversion to XHTML. The hard part is constructing a site so that it stays valid XML no matter what you or or anyone else throws at it.
The lack of XHTML applications has a more insidious effect in that it raises the cost/benefit ratio for converting to XHTML. We can convert, but most of us won’t be doing anything with it — the benefit is low. As for the cost, that can be surprisingly high.”
