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.
