This makes it possible to apply filters to constants.
[(#VAL{<:chaine_de_langue:>}|image_typo)]
(which is equivalent to <:chaine_de_langue|image_typo:>
)
Example
If you wanted to assign a (.css) stylesheet for each day of the week, you could that with the following code:
[<link rel="stylesheet"
href="squelettes/styles/jour_(#VAL{w}|date{#DATE|strtotime}).css"
type="text/css" />]
The stylesheets would be named respectively from jour_0.css
through jour_6.css
(translated as: jour_sunday.css through jour_saturday.css)
