What about evolving standards in a system that must handle clients or servers which implement anything from tomorrows feature today to 10 years prior. Shouldn't failures be as graceful as possible?
No, now or 10 years later, syntax error (like unclosed tag or missing quote) is a syntax error. Ignoring it is always a bad idea.
Unknown tags / attributes, on the other hand, may be ignored for future compatibility.. but I believe XHTML ignores them already.
