Thank you Hans.

With \defineenumeration, adding an explicit \par for the footnote allows 
the index to print in the margin, and it works as well with 
multi-paragraph footnotes using \epar and \bpar.

However, this does not address the failure to indent when the ID starts 
a paragraph.

This does nothing to address the issues with \definelabel, but 
\defineenumeration, together with "don't do that" for paragraph starts, 
may now suffice.
