Use tag instead of urn URI scheme for IDs

[mibe]

During researching for PR #33 I noticed that for ATOM IDs the code is using the urn URI scheme. This is not wrong per se, but IMHO the tag scheme is better. I've checked the ATOM feeds of some big sites, and all were using the tag scheme. It doesn't need a registration at IANA and also contains more information than a simple UUID.

Here are some opinions and information:

• How to make a good ID in Atom
• Tag URI
• The tag URI scheme: a simpler, more democratic URN

What do you guys think about that?

Highly appreciated. Actually, the urn:uuid is not always neccessary, as far as I researched now. Acutally, it seems to prevent RSS readers to read any further than one item in my setup. So the tag method seems to be a better way to go IMHO.

Weird, BTW: No matter what I pass on with $newItem->setId($url), all UUID for every Entry remain the same?! Is there any reason for that and how I could fix this?

Can you open a new issue for that?
