tree-editor does not allow editing of non-referenced material following a referenced creator
There is a problem with how the tree editor handles referenced content. In document knb-lter-sbc.15.6, the protocol/creator is a reference to another responsibleParty. Morpho's tree editor dims all the content after the creator with the term 'REFERENCE'. If you open up just the methodStep, then the rest of the method node after the creator is dimmed. If you open up the dataset node, then all the EML following the protocol/creator is dimmed out. If you select a node from the menu it is displayed properly if no referenced creator is within it. I did not check the behavior on any other referenced elements.
this is an excerpt of knb-lter-sbc.15.6, with a referenced protocol/creator:
<title>SBCLTER Cover Protocol</title>
for comparison, doc knb-lter.sbc.6.2 has no referenced protocol/creators.
