Description:

The XSD for intent qualifiers does not provide for any extensibility.

The intent complex type has the usual <any/> as part of its definition:

       <complexType name="Intent">
               <sequence>
                       <element name="description" type="string"
minOccurs="0"
                          maxOccurs="1" />
                       <element name="qualifier"
type="sca:IntentQualifier"
                          minOccurs="0" maxOccurs="unbounded" />
                       <any namespace="##other" processContents="lax"
                          minOccurs="0" maxOccurs="unbounded"/>
               </sequence>
               <attribute name="name" type="NCName" use="required"/>
               <attribute name="constrains" type="sca:listOfQNames"
                  use="optional"/>
               <attribute name="requires" type="sca:listOfQNames"
                  use="optional"/>
               <attribute name="excludes" type="sca:listOfQNames"
                  use="optional"/>
               <attribute name="mutuallyExclusive" type="boolean"
                  use="optional" default="false"/>
               <attribute name="intentType"
                       type="sca:InteractionOrImplementation"
                       use="optional" default="interaction"/>
               <anyAttribute namespace="##other" processContents="lax"/>
       </complexType>

...by contrast, the IntentQualifier type has no such extension point:

       <complexType name="IntentQualifier">
               <sequence>
                       <element name="description" type="string"
minOccurs="0"
                          maxOccurs="1" />
               </sequence>
                 <attribute name="name" type="NCName" use="required"/>
                 <attribute name="default" type="boolean" use="optional"
                    default="false"/>
       </complexType>

This looks like an oversight and should be corrected since no extension of
IntentQualifier
is permitted.

Proposal:

A simple change is to add

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

at the end of the sequence in the IntentQualifier definition.
