The answer is clearly set forth in login.conf(5):

 "Records in a class capabilities database consist of a number of colon-
     separated fields.  The first entry for each record gives one or more
     names that a record is to be known by, each separated by a '|' character.
     The first name is the most common abbreviation.  The last name given
     should be a long name that is more descriptive of the capability entry,
     and all others are synonyms.  All names but the last should be in lower
     case and contain no blanks; the last name may contain upper case charac-
     ters and blanks for readability.

     Note that since a colon (`:') is used to separate capability entries, a
     `\c' escape sequence must be used to embed a literal colon in the value
     or name of a capability."

When in doubt, look for a manpage (first).
