I've downloaded prettify.css/prettify.js code from bootstrap repository for my project and I realized that it doesn't highlight my xml/html code w/o linenums class.
I thinik, Its more easy to download google-prettify code from bootstrap repo (not from official site) because its already stylized to main bootstrap theme. I guess loads of users do that (not only me) and they can find this issue in their projects.
So, in case if user decided to prettify his html/xml code w/o "linenums" class, he wouldn't get any highlight from prettify.js due to forgotten comma betwen "linenums" and "tag" classes in css.
