Correct. Fragment identifiers must start with [A-Za-z].
<http://www.w3.org/TR/html4/types.html#type-cdata> says "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 (".").".
The current incarnation of HTML 5 only says that spaces are illegal:
<http://www.whatwg.org/specs/web-apps/current-work/multipage/section-global.html#the-id>.
But that may well change still and it will anyway be quite a while before
HTML 5 is an actual spec.
