Re: [sca-assembly] Issue 17 proposal

[Mike Edwards <mike_edwards@uk.ibm.com>]

Anish,

Just reading over one of the emails
from earlier this month and I realize that I dont understand the
significance of something you said here

- what do you mean when you say "SCA
does not define a component model a la WSDL 2.0" ??

- what would it mean for SCA to have
a formal component model and what difference would it make
to the current discussion?
