> Suggested approach would be to parse El expression and afterwards execute less processor.
> Server-side mechanism must be available for executing less.
> Approach 1 : end-user chooses less or ecss but cannot mix the 2 syntax in the same file.
> Approach 2 : allow end-user to use less syntax in ecss files
>  * modify current ecss execution (evaluate EL expression and don't parse CSS anymore)
>  * add a less compilator afterwards.
> Less compilation at build time or runtime ?
> For both of these 2 approaches, less compilation can be done built-time or execution time (need to investigate more to choose the right approach).
> If build time, richfaces-resources-maven-pluginwould be a candidate to execute El and less compilation.
