Re: Agenda Topic / Issue: Clarify the meaning of "ignore" with respect to attributes that have no legal value

Can I also clarify, just to round this out, that in this test case  
from Philip:

<p xmlns:ex="http://example.org/">
   <span property="ex:test1" href="http://example.org/href">Test</span>
   <span rel="ex:test2" property="ex:test3" href="http://example.org/href 
">Test</span>
   <span rel="" property="ex:test5" href="http://example.org/ 
href">Test</span>
</p>

the triples are:

(from the first <span>)
   <http://example.org/href> ex:test1 "Test" .

(from the second <span>)
   <> ex:test2 <http://example.org/href> .
   <> ex:test3 "Test" .

(from the third <span>)
   <> ex:test5 <http://example.org/href> .

In other words that the empty rel attribute is treated differently  
from a rel attribute that contains only illegal CURIEs, which is  
treated the same as a missing rel attribute.

Thanks,

Jeni
