Template Editable tag attributes removes editable region
Hi,
I have a nested template.
In it's parent template I have several editable regions, one of them is for the document title:
<title>
<!-- InstanceBeginEditable name="title" -->
DnD-Production
<!-- InstanceEndEditable -->
</title>
I am trying to add an editable text attribute in the nested template, in a "submit" form, which is near the bottom of my doc
Before:
<input name="orderSubject" type="hidden" value="formValue" />
I use the editable tag attribute:

after:
<input name="orderSubject" type="hidden" value="@@(submitValue)@@" />
The problem is that it also places the TemplateParam in the middle of the "title" editable region.
<title>
<!-- InstanceBeginEditable name="title" -->
DnD-Production
<!-- TemplateParam name="submitValue" type="text" value="formValue" -->
<!-- InstanceEndEditable -->
</title>
This causes a problem because when i try to update descendant pages i get a message that the "title" region is unresolved

Is this normal? Am i doing something wrong here?
How can I fix this, I mean add the editable text without removing the title editable region?
