May be you could:
* Initialize a variable in my.insert to 0.
* Set it to 1 in my.insertId just after <cfg:command name="prompt"/>
* Test it in my.insert.
A variable shared by multiple macros must have a name in the
"http://www.xmlmind.com/xmleditor/namespace/scope/view"; namespace.
See http://www.xmlmind.com/xmleditor/_distrib/doc/commands/xpath_vars.html
Example:
---
<set ns:done
xmlns:ns="http://www.xmlmind.com/xmleditor/namespace/scope/view";
expression="1" />
---
(I've not tested this. This is just an idea.)
