Specifying parameter type in .xml where parameter is a class defined in python

Hello,

I have a block “ldpc_encoder”, which takes as parameter an object of the
class “ldpc_parity”.The block “ldpc_encoder” and the class “ldpc_parity”
are defined in python. The parameter is passed as a variable LDPC_Parity
into the init() method. I have successfully installed this block
using
cmake tools.

Now I want to edit .xml file corresponding to this block. The
automatically
generated(using mod_tool) .xml file is given below.

<?xml version="1.0"?> ldpc_encoder ldpc_ldpc_encoder ldpc import ldpc ldpc.ldpc_encoder($LDPC_Parity) ... ... ... in out

From what I understand, I have to edit the parameter declaration to
define $LDPC_Parity as a parameter.
How do I specify the type in this case? Can I use import statements?

Another question with reference to the earlier mail.
The input/output vector length are variables K and N respectively which
are
computed inside the init() method. So how can I specify vlen tag
under
sink/source tags?
