It's not a comment; it's a normative statement; it says that the
function name, although a name, is not added to the compression table.

The "entities appearing in syntax tables" statement is a non-normative
remark, though. The function certainly appears in the syntax table (at
least in gcc, and in any other compiler).

  I think that the name of a template is (since you can't

Well, <function name> is still part of <encoding>...
