Why is a table inserted into my referable-content topic as a choicetable?
This is the expected behavior based on the model of the <rcbody> element.
Symptom
When inserting a table into a referable-content topic, the table is inserted as a choicetable instead of a regular table.
Problem
This is the expected behavior based on the model of the <rcbody> element, which is defined to include "ANY" element. When you insert a table, Oxygen looks at the context and provides the appropriate dialog: Insert Choice Table or Insert Table. A choicetable has a very specific context and does not normally overlap with the table/simpletable context. However, in the case of a referable-content topic, choicetable does overlap with table/simpletable. In this case, Oxygen presents the first qualifying dialog available, Insert Choice Table.
Solution
Add a table to your referable-content topic template. If users don't need a table in the referable-content topic that they're creating, they can delete it.
