Hi Smith,

A precedent for use of "_" (underscore) to separate base and
extension names is section 3.4 Derived Media Type Names of
MSN2 (PWG5101.1-2013) [1], which begins with the following:

"Media Type Names MAY be locally extended from existing standard,
vendor, or custom media names by prefixing the names with the string
"derived-" and appending the existing name with a leading underscore,
e.g., "derived-xyz-photo_photographic-glossy".  The format is defined
by the following ABNF [STD68]:

    derived-type-name = "derived-" base-name "_"
                      ( base-name / vendor-type-name /
                        custom-type-name )

Cheers,
- Ira
