Arbortext Editor: How to show processing instruction in cals-table?

Hi,

in one of our xml-workflow we must insert a processing instructions before the <row>-Element within a cals-table.

If we do this, unfortunately we cannot see this pi in the Arbortext Editor table-view:

As you can see the processing instruction is hidden. Only if we activate the markup view in tables, we can see the pi, but unfortunately in a non user-friendly view of the cals-table with markups:

Does anybody has an idea how we can visualize the inserted pi for the users?

We tried to do this with styler but without success. We use Arbortext Editor 6.1.M060.

Thank you in advance for your help.
