Are there any invalid values from id that use only [a-z0-9]?

I'm generating IDs for elements in a page, and would like to make sure I don't stumble across some invalid 'id' value. While the W3 standard seems to say that anything goes, you never know about all browsers, etc, so I'm asking here.

I'm talking about id as in <div id='myid' />.

ID (and NAME) tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").
