[antlr-interest] About Template Call (String Template)

[gaochunguang]

String Template3.1 for .net

when my group file is :
parser(name) ::= "<type(name=\"gao\")>";
type(name) ::= "type <name>"

output is 
 type gao. 

but if my group file is :

parser(name) ::= <<
 <type(name=\"gao\")>";
>>
type(name) ::= "type <name>"
output is nothing. why multi line template cannot work?
