The names of certain syntaxes are constructed from syntax templates. A syntax template is a lexical construct comprising a primary identifier followed by a * (asterisk) enclosed in parentheses, as follows:
identifier (*)
A syntax template encompasses a group of related syntaxes. Any member of the group, without distinction, is indicated by the primary identifier (identifier) alone. A particular member is indicated by the template with the asterisk replaced by one of a set of secondary identifiers associated with the template, as follows:
identifier1 (identifier2)
