I suppose that
   <weird_element>with a content </weird_element>
is considered equivalent to
   <weird_element>with a content </weird_element>
which is valid well-formed XML.

Note the comment on rule 44:
For interoperability, the empty-element tag must be used, and can only be 
used, for elements which are declared EMPTY.

I assume that a XML processor that enforce the interoperability 
recommendations would flag an error for your example.
