[sca-j] NEW ISSUE: SCA Spring C & I specification should make typeattribute as optional for <sca:service/> element

Raiser:   Ramkumar Ramalingam

Target:  SCA Spring C&I

Description:
The SCA Spring Client and Implementation specification should make the
type attribute as optional for the <sca:service/> element in the
SCA Spring Extension Schema.

Lets assume a scenario where the existing
spring application is used as a SCA component, in such cases its possible
to have spring beans that do not have any implemented interfaces. So when
the user wants to explicitly expose a particular spring bean (which does
not implement any interface) as sca service using <sca:service/>
element by just modifying the spring context xml file, then the current
<sca:service/> element does not allow the user to do the same, as
it mandates to specify the interface implemented by the bean as value for
its required type attribute.

Proposal:
For Java implementations, in absence of
annotations, the impl class is used as the interface (§1.2.1.3 of the
OSOA Java Impl spec).
Similarly in this case, the SCA Spring
C&I specs should make the "type" attribute as optional for
the <sca:service/> element,
and allow the users to expose a bean without
any implemented interface as service, by assuming that the impl class to
be used as interface for the service.
