LC comment: Ambiguous "otherwise" step

Section 5.5 step #4
 >/otherwise/, if [parent object] is present, [new subject] is set to 
that /and/ the [skip element] flag is set to 'true';

Spec is unclear on what to do if processing gets to this final step and 
[parent object] is not "present" and ("present" should be more specific, 
e.g. "not null").

Additionally, it seems like an error to set the [skip element] flag in 
this step. In the case of an element with @property and no other 
attributes, the element definitely shouldn't be skipped.
