Fabien, 

Thank you _very_ much. Great job! We (Wing and I) are certainly
going to work through it and address all of the open issues.
Please allow us some time to elaborate on this ...

The JUnit test suite sounds very interesting - any chances we can
use it on a public basis?

If appropriate, may we include your three new TC into the official
suite?

Regarding the XMLLiteral issue (TC 13): 
Did you have a look at [1], already? If yes, feel free to add an
according 
question (best with source code :) there, if not, pls have a look at
this
Wiki page, and tell us if it answers your question or what is still
missing.

Now, trying to answer some of your questions:

>Question #1: Where do I get the URL of the source document from?
>The current stylesheet tests if there is a xml:base. If there 
>is no xml:base it tests if the parameter URL was past to it. 
>If not the default value is "".

IMHO this is correct, looking at [2] and [3] (resolved issues).

>Question #2: What happened to the use of "class" attribute?
>Since I found no trace of it in the tests and in the syntax, I 
>deactivated its use in the transformation.

Hm. IIRC, this is still in flux, see Tracker [4]. 
We certainly have to resolve this one; the latest thread on
the RDFa list I am aware of is [5].

@Ben: I've just updated the Tracker issue 3, maybe an agenda item for
today?

Cheers,
	Michael
