Here is: My question was not "how do I do it with XEmacs". It was "why does XEmacs do it this way". The `foo-bar-p' runtime-type-check predicates like `commandp', `functionp', `keymapp', `facep', `markerp', `stringp', `hash-table-p', `char-table-p' are traditionally linked to the functions that operate on them such that: - (functionp foo) is non-nil iff you can pass `foo' to `funcall'. - (commandp foo) is non-nil iff you can pass `foo' to `command-execute'. - (keymapp foo) is non-nil iff you can pass it to `lookp-key'. ... I'd thus expect that (facep foo) should return non-nil iff foo can be passed to set-face- and similar functions. Stefan
