[antlr-interest] [ST] How subtemplates work?

Hi!

I have looked for subtemplates working examples or how subtemplates  
work in the ST wiki but I haven't managed to find out.

My question is, with this StringTemplate GroupFile:


pnml(xmlns) ::= <<
<pnml xmlns="$xmlns$">
   $net$
</pnml>
 >>

net(id, type) ::= <<
<net id="$id$" type="$type$">
   foobar
</net>
 >>


How should I implement my .g file to make the pnml template make use  
of net template?
For example:


grammar Test1;

options {output = template;}

s	:	INT '&' ID '&' net ';' -> pnml(xmlns={$INT.text}) ;
net	:	ID -> net(id={$ID.text},type={$ID.text}) ;
ID	:	'a'..'z'+ ;
INT	:	'0'..'9'+ ('.' '0'..'9'+)+ ;
WS	:	(' '|'\t'|'\n'|'\r') {skip();} ;

Which is not correct...

Thanks in advance,
Cris.
