Recently a reply I wrote got rejected for an unacceptable tag; the "tag" turned out to be the less-than-or-equal combination: < =
Adding a space (as above) got the message accepted, but I wonder whether the particular combination (less than; equal; space) could be explicitly accepted by the message system.

Hilmar.
