[xml] Validation bug?

[Frank <fweenink xs4all nl>]

Hi,

When validating the following document against the dtd, libxml does not 
give a validation error, while Xerces and nsgmls did.

<ROOT>
<A/>
<B/>
</ROOT>

<!ELEMENT       ROOT    (A* | B*)>
<!ELEMENT       A       EMPTY   >
<!ELEMENT       B       EMPTY   >

I also tried this with the cvs snapshot but I'm not sure I that the 
right way, because of an already installed version on the same computer. 
I searched bugzilla for this bug (but did not find it).

Is it me or is this a bug?

Regards,

Frank.
