group group-name (& group-name)*


group indicates that the rules following this declaration are part of the named groups. More than one group declaration can name the same group: the rules following every group declaration for a given group name are members of the named group.

The following variations are permitted:

  • the keyword and can be used in place of &, and
  • the list of group names may be placed in parentheses to improve readability.

Declarations and functions are not affected by groups. The selection of an error rule (markup-error or sgml-error) is also unaffected by which groups are currently active.
