That's what I hoped. My xml document is first processed by other software
that excludes inlineequations in tables and numbers the remaining
inlineequations consecutively. I have to process the inlineequations exactly
the same way to give the inlineequations the same number as given by the
other software.

It would have been much easier just to number it.

Thanks.
