One HTML WG decision I agree with is the one associated with Issue 120 on RDFa prefixes.
Considering that RDFa support in XHTML/HTML to this point has made use of prefixes, I don’t understand why we even contemplated not supporting prefixes just because RDFa is being ported to HTML5. Frankly, it’s not the HTML5 WG’s design decision to make—RDFa in HTML5 is a port, the design for RDFa resides with another group.
As for RDFa prefixes being confusing, one of the most fundamental design patterns, in computer tech and elsewhere, is the concept of variable/value pairs, with a shorter, easy to type and remember variable or abbreviation used in place of a longer, more complex value.
Then there’s the fact that RDFa has significant adoption, and dropping support for prefixes will break the web. I’ve heard that this is an important criteria for other HTML5 design decisions. If nothing else, consistency demands we support prefixes.
I could go on, but the proposal to keep prefixes does a commendable job and I don’t need to repeat its arguments.
