Re: ISSUE-40 Comment on RDFa 1.1 Core: Empty elements should not create literals

I am sympathetic to the original proposal in this issue.  However, it 
raised the following concern for me:

In this case, I believe there are no child nodes at all.  Not sure what 
my parser would do if it encountered the following:

    <span property="p1"></span>
       


No child elements are text nodes, so it would be a plain literal, but 
since there are no descendant nodes in the DOM at all...  the value of 
that plain literal could be undefined or "".  Obviously the supposition 
is that the plain literal starts as "" and then text node values would 
get appended to it.  But we don't say that.  We probably should.
