[Mediawiki-l] Passing template variables to extension

[Fernando Correia]

I'm trying to create a template to encapsulate an extension. I'd like
to call the extension passing the template parameters. Something like:

<extension-tag name="{{{1}}}" />

The problem is that the extension receives the string "{{{1}}}" and
not the actual parameter. Searching this mailing list I found out that
other users had the same problem but I could not find a definite
answer.

Is there a way to do this?
