This special form temporarily adds specifications to specifiers,
evaluates forms in @var{body} and restores the specifiers to their
previous states. The specifiers and their temporary specifications are

This function adds some specifications to @var{specifier}. @var{value}
can be a single instantiator or tagged instantiator (added as a global
specification), a list of tagged and/or untagged instantiators (added as
reasonable form. More specifically, @var{value} can be anything
accepted by @code{canonicalize-spec-list}.

+@var{locale}, @var{tag-set}, and @var{how-to-add} are the same as in
+@code{add-spec-to-specifier}.
Note that @code{set-specifier} is exactly complementary to
@code{specifier-specs} except in the case where @var{specifier} has no

specification for that locale will be returned.

@code{buffer}, @code{frame}, or @code{device}), a spec-list of the
specifications for all locales of that type will be returned.
Only instantiators where @var{tag-set} (a list of zero or more tags) is
a subset of (or possibly equal to) the instantiator's tag set are
-returned. (The default value of@code{ nil} is a subset of all tag sets,

is non-@code{nil}, however, @var{tag-set} must be equal to an
instantiator's tag set for the instantiator to be returned.
and can further be restricted to a particular device-type or device-class.
Specifiers are used, for example, for the various built-in properties of a
face; this allows a face to have different values in different frames,
-buffers, etc. For more information, see `specifier-instance',
-`specifier-specs', and `add-spec-to-specifier'; or, for a detailed

+@code{specifier-specs}, and @code{add-spec-to-specifier}; or, for a detailed
description of specifiers, including how they are instantiated over a
particular domain (i.e. how their value in that domain is determined),
see the chapter on specifiers in the XEmacs Lisp Reference Manual.
