I had a look and yes, 'description' had it as a plain required element. I changed it to oneOrMore.

For 'license', though, it is indeed zeroOrMore because of our resolution to Issue 18 license element text subelements

http://dev.w3.org/webfonts/WOFF/DoC/issues-lc-2010.html#issue-18

in other words we decided that text was optional, because sometimes people want to only link to a license and not summarize or duplicate it as text.
