[uf-discuss] Generating valid unique IDs for hAtom

I've been looking into generating unique references for entries that can
be used in the id attribute for an hAtom implementation. Does anyone
actually have a solution for this?
I've been using something along the lines of:
It's valid HTML, but not a proper tag URI as far as I can tell from RFC
4151. Would it be worth coming up with a microformat standard for people
to follow that is valid HTML, using [A-Za-z][A-Za-z0-9_:\.-]? Tag URIs
don't work and neither do permalinks? Is there another standard we can use?
Incidentally, from the microformats wiki:
"the syntax of tag URIs and html id attributes are incompatible. HTML
disallows forward-slash (/) in ids 
(http://www.w3.org/TR/html401/types.html#type-name), while tag URIs
I'm too afraid of getting shouted at to go and edit the wiki, but this
doesn't sound right to me? Forward slashes aren't *required* by the tag
URI specification as far as I can see, but commas *are* required and not
permitted in HTML:
It still renders tag URIs inappropriate, but I think the details are
wrong and might want correcting.
