This include file defines some standard support tags one needs all the time.
All tags are self-explanatory and briefly mentioned in wml_intro(1), except
the last two which are described below.
This tag was primarily a shorthand for <script
type="text/javascript" language="JavaScript"E<gt> but
it has evolved. If the <head> tag is defined and is a
complex macro, e.g. when calling wml::std::page, then Javascript code
is automatically passed to this macro and should be diverted to the HEAD
section of HTML documents. This diversion preserve lang slices in
multi-lingual documents. Those features may be disabled by the ``nohead''
and ``nolang'' attributes.
WML tries to print information on input file and line numbers when
warnings or errors are reported in passes 2 and 3. Some special
sentences containing file names and line numbers are inserted during
pass 1. So pass 2 have an accurate knowledge of where warnings appear in
input file. But it also filters it without preserving lines, so
after pass 2 information is almost unusable. By putting
<sync-lines> in input file, it forces pass 2 to resynchronize
information on line numbers. So for debugging pass 3, it could be of
some help to insert <sync-lines> before ePerl code.
