I'm still a bit confused.  I understand why there was a problem with:

[mytag title="[item-field title]"]

However I do not understand why this fixes it and how it differs in IC's
eyes:

[tmp title][item-field title][/tmp]
[mytag title="[scratch title]"]

Also your original example used [tmp title] and your most recent example
uses [tmpn title], both seem to work properly, is one preferred over the
other?

If I went this route then I would need to parse the parameters contained
within the body, since I will be passing more then one field.  Which
would be more efficient writing a parse routine for the  body text, or
using the [tmp] setting? 

Thanks again for your help, trying to understand IC better :)
