Re: RDF Containers in XUL Trees

No but it will allow me to test whether a resource has the property of 
'my:Container' rather than just the generic 'rdf:Seq'. It just seemed to 
make more sense semantically.

If I use the following RDF the tree doesn't build:

<my:Container rdf:about="level1" my:name="Parent">
   <rdf:instanceOf
       rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq"/>
   <rdf:li rdf:resource="level2"/>
</my:Container>

<my:Container rdf:about="level2" my:name="Child">
   <rdf:instanceOf
       rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq"/>
   <rdf:li rdf:resource="level3"/>
</my:Container>

If I swap the 'my:Container' class for 'rdf:Seq' it builds fine.

I take it this is what you mean by:

 > Mixing rdf:li with other parents is likely to achieve brokeness.

So in theory at least, how does the tree consider an assertion a container?

As in rdf:Seq, rdf:Bag, rdf:Alt
