[NEW ISSUE] A.11 sca-contribution.xsd incorrectly requires <deployable/> element

Description:

In the sca-contribution.xsd, the declaration
of the <contribution/> element has a sequence of subelements 
starting with <deployable/>.  In
the XSD, the declaration of <deployable/> has maxOccurs="unbounded"
but
no minOccurs atribute, with the result
that this element is a REQUIRED subelement (there must always be
one).

This contradicts the main text of the
spec in Section 12 and also the pseudo-schema, which indicates that
the <deployable/> element is optional.
 It is necessary for the <deployable/> element to be missing
for
cases of contributions that are not
in themselves deployable, but which provide artifacts for other
contributions to use.

   <!--
Contribution -->
   <element
name="contribution"
type="sca:ContributionType"/>
   <complexType
name="ContributionType">
      <complexContent>
         <extension
base="sca:CommonExtensionBase">
         
  <sequence>
         
     <element
name="deployable"
type="sca:DeployableType"

     
                  maxOccurs="unbounded"/>
         
     <element
ref="sca:importBase"
minOccurs="0"

     
                  maxOccurs="unbounded"/>
         
     <element
ref="sca:exportBase"
minOccurs="0"

     
                  maxOccurs="unbounded"/>
         
     <any
namespace="##other"
processContents="lax"
minOccurs="0"

     
                  maxOccurs="unbounded"/>
         
  </sequence>
         </extension>
      </complexContent>
   </complexType>

Proposal:

Add a minOccurs="0" attribute
to the declaration of the <deployable/> element:

   <!--
Contribution -->
   <element
name="contribution"
type="sca:ContributionType"/>
   <complexType
name="ContributionType">
      <complexContent>
         <extension
base="sca:CommonExtensionBase">
         
  <sequence>
         
     <element
name="deployable"
type="sca:DeployableType"

     
                  minOccurs="0"
maxOccurs="unbounded"/>
         
     <element
ref="sca:importBase"
minOccurs="0"

     
                  maxOccurs="unbounded"/>
         
     <element
ref="sca:exportBase"
minOccurs="0"

     
                  maxOccurs="unbounded"/>
         
     <any
namespace="##other"
processContents="lax"
minOccurs="0"

     
                  maxOccurs="unbounded"/>
         
  </sequence>
         </extension>
      </complexContent>
   </complexType>
