Using W3C spec text on WPD

One of the folks at our mini-hackathon wanted to include a few sentences of
text from the official spec in the article.

However, looking at the license of the specs (
http://www.w3.org/Consortium/Legal/2002/copyright-documents-20021231) , it
appears that we'd have to jump through a fair number of hoops to include
that content on the page.

Is there guidance on how we should include text from W3C specs on the site?
For now we just held off.
