manvolnum — A reference volume number
Mixed Content Model
The notion of a volume number is historical. UNIX manual pages (“man pages”), for which
RefEntry was devised, were typically stored in three ring binders. Each bound manual was a volume in a set and contained information about a particular class of things. For example, volume 1 was for user commands, and volume 8 was for administrator commands.
Volume numbers need not be strictly numerical; volume “l” frequently held manual pages for local additions to the system, and the X Window System manual pages had an “x” in the volume number: for example, 1x.
The content of
ManVolNum is usually printed in parentheses after the element title or citation.
