This can easily be overcome by adding both types to your .mailcap file
(for UNIX) or the MOSAIC.INI (for PC-Mosaic). There will be similar
files for other browsers and/or otehr platforms.

It means that it is a proposed standard, rather than a ratified
one, and you will find it in some of the other MIME types. When Henry
and I put forward chemical/ as a MIME type the subtypes were are x-*.
We are now putting forward the second draft
(http://www.ch.ic.ac.uk/chemime.html) and if accepted, the x- will be
dropped for those filetypes in it. Other new proposals would, strictly
speaking, have the x- until the chemical/ community ratified it.
The acceptance of chemical/ has been so rapid that as a de facto
standard, we are suggesting that servers drop the x-, but it will be a
little while before there is consistency.
