Bug in Kannel WML Compiler??

Hello all,
I suspect that there is a small bug in the Kannel WML compiler.
The bug is related to variable substitution as specified in 
http://www.openmobilealliance.org/tech/affiliates/wap/wap-191-wml-20000219-a
.pdf
. Section 10.3.1 Variable Substitution says:

"If no conversion is specified, the variable is substituted using the 
conversion format appropriate for the context. All attributes defined 
as %HREF; default to escape conversion, elsewhere no conversion is 
done. Specifying the noesc conversion disables context sensitive 
escaping of a variable."

The WML binary standard does not provide a token for a variable
substitution without conversion (the defined tokens are EXT_I_0
..EXT_I_2, EXT_T_0..EXT_T_2), that's why the WML compiler has to choose
the correct one. Currently the WML compiler unconditionaly uses
the "noesc" conversion for all contexts, even in the href attribute:
http://www.kannel.org/cgi-bin/lxr/source/gateway/gw/wml_compiler.c#L1107

Unfortunately the function "check_variable_syntax" does not even
know the context. Any suggestions?

Regards
