[plt-scheme] reading HTML as XML

I'm officially maintaining the XML collection.

In the comments to xml->xexpr it says "The contract is loosely
enforced." and looking at all the uses of it in the PLT tree, it
doesn't seem to matter, because all the uses obey the contract.

If I turn back on the contract enforcement, there aren't any errors in
the test suite. So, I turned it on in SVN.
