[stringtemplate-interest] Referense template in other file.

Thanks Terence. I have solved this problem by creating base group, which
contains all shared templates i need and deriving from it.

I have another question.

Lets assume i have  a simple group definition:

group simplegroup;

mypage(title, content) ::= <<
<html>
    <title>$title$</title>
    <body>
        $content$
    </body>
</html>
>>

Documentation says that i can set default value for the formal parameters of
template. So i could rewrite my template as:

mypage(title = "Default Page", content = "Default Content") ::= <<
.............
>>

But can i set other template, defined in the same group, as default value?
Something like this:

mypage(title = "Default Page", content = defaultContent()) ::= <<
.............
>>

defaultContent() ::= "Default Content"

I have tried this and got the error. However, i have tried to pass template
defined in derived group into referenced template defined in base group, as
argument and it works.

Sorry for plenty of questions :) I'm just evaluating ST# to use as view
engine in my projects, trying to learn it and understand what is the best
way to organize templates.
