      Hi,

during the implementation of the current spec an inconsistency
between the description of the Term Compositor Structure (page 16
in the latest sourceforge version of the spec) and the schema
description on page 46. We suggest to replace this description:

     <xs:element name="All" type="wsag:TermCompositorType"/>
     <xs:complexType name="TermCompositorType">
         <xs:sequence>
             <xs:choice maxOccurs="unbounded">
                 <xs:element name="ExactlyOne" type="wsag:TermCompositorType"/>
                 <xs:element name="OneOrMore" type="wsag:TermCompositorType"/>
                 <xs:element ref="wsag:All"/>
                 <xs:element name="ServiceDescriptionTerm" 
type="wsag:ServiceDescriptionTermType"/>
                 <xs:element name="ServiceReference" 
type="wsag:ServiceReferenceType"/>
                 <xs:element name="ServiceProperties" 
type="wsag:ServicePropertiesType"/>
                 <xs:element name="GuaranteeTerm" type="wsag:GuaranteeTermType"/>
             </xs:choice>
         </xs:sequence>
     </xs:complexType>

with the following:

     <xs:element name="All" type="wsag:TermCompositorType"/>
     <xs:complexType name="TermCompositorType">
         <xs:sequence>
             <xs:choice maxOccurs="unbounded">
                 <xs:element name="ExactlyOne" type="wsag:TermCompositorType"/>
                 <xs:element name="OneOrMore" type="wsag:TermCompositorType"/>
                 <xs:element ref="wsag:All"/>
                 <xs:element name="Service" type="wsag:ServiceType"/>
             </xs:choice>
         </xs:sequence>
     </xs:complexType>
     <xs:complexType name="ServiceType">
         <xs:sequence>
               <xs:element name="ServiceDescriptionTerm" 
type="wsag:ServiceDescriptionTermType" maxOccurs="unbounded"/>
               <xs:element name="ServiceReference" 
type="wsag:ServiceReferenceType" minOccurs="0" maxOccurs="unbounded"/>
               <xs:element name="ServiceProperties" 
type="wsag:ServicePropertiesType" minOccurs="0" maxOccurs="unbounded"/>
               <xs:element name="GuaranteeTerm" type="wsag:GuaranteeTermType" 
minOccurs="0" maxOccurs="unbounded"/>
         </xs:sequence>
     </xs:complexType>

In addition to allow the implementation of what is described in page 16
the structure is more easy to understand after separating the definition of
the ServiceType object from the TermCompositorType

Best regards

Wolfgang
