UI Template Substitution tags in a procedure

Question

Version: 10.1.4
Is it possible to use Substitution tags in a procedure and call the procedure with in the UI template?
So the UI template will be:
<ORACLE>
BEGIN
Schema.procedureName;
END;
</ORACLE>
The procedure will be:
PROCEDURE procedureName as
BEGIN
htp.p('#USER.FULLNAME#');
END;
This way all the logic can be built in the procedure (taking advantage of the Substitution tags).
When I tried the above the Substitution tag is not rendered as it supposed to (display the User Full Name), but just displays it as raw HTML.
Is it possible/viable to use Substitution tags outside UI Templates?
Thanks.

The specific example you are asking about could also be implemented without substitution tags. The following is from a pl/sql item I added in my footer. Hope it's of use to you:
declare
l_person_rec wwsec_person%rowtype;
begin
htp.print('<div class=PortletText1>');
l_person_rec := wwsec_api.person_info( wwctx_api.get_user_id() );
if (l_person_rec.first_name = 'PUBLIC') then
   htp.print(l_person_rec.first_name);
else
   htp.print(l_person_rec.first_name || ' ' || l_person_rec.last_name);
end if;
begin
   htp.print('(' || wwsec_api.group_info(wwsec_api.get_defaultgroup()).name ||
exception when others then
   null;
end;
htp.print('</div>');
end;
