The <navbar:define> tag defines the grammar, it has nothing to do
with rendering or appearance. It's why i think you should remove the
``nohints'' attribute from this tag too. You may object that the
``txtcol_normal'' and ``txtcol_select'' attributes are also about
rendering. I agree and think they should go to <navbar:render> (looks
like we think too muck ;-))

Without these 6 statements, the code is easier to debug and maintain ;-)

I have slightly modified wml::std::lang to help customization. The
wildcard used in the <lang:star:> tags can be redefined, e.g.
  <lang:set-wildcard %>

Lazy people who want to save keystrokes may read this example
(with wml-SNAP > 07-Apr-1999)

###   Begin example
<lang:set-wildcard %>
<define-tag navbar:lazy>
<%%eval
  <subst-in-string
    <subst-in-string "<XNAVBAR:button %body>"
        "%" "<lang:star: %>">
  XNAVBAR navbar>
>
</define-tag>

<navbar:define name=test>
  <navbar:button img="<lang:star: foo-%>-*.gif"
                 url="<lang:star: foo.%.html>"
                 txt="<de: Hallo><en: Hello>">
#    Does the same job
  <navbar:lazy img="foo-%-*.gif"
               url="foo.%.html"
               txt="<de: Hallo><en: Hello>">
</navbar:define>
#    Restore default value
<lang:set-wildcard>
###   End example

I'm afraid i am :-(. But it's your code, so _you_ decide. Tell me when
you want to upgrade wml_contrib/navbar-FH.wml, i will.
