Application-specific data in Streams and ENERGYINTEROP-504

I like the applicationSpecificSignalBase in the following fragment
from EiClasses.xsd, wd29-wip2. In a previous email I said that  in
wd29-wip2 the SignalLevelType is (largely) an xs:choice; I've
highlighted the element that's the subject of this email in
Bold
Italic  .
    <xs:complexType
name= SignalLevelType >
        <xs:annotation>
            <xs:documentation>The Signal Level is a Stream
Payload holding a single value.</xs:documentation>
        </xs:annotation>
        <xs:complexContent>
            <xs:extension base= eitc:StreamPayloadBaseType >
                <xs:sequence>
                    <xs:choice minOccurs= 1  maxOccurs= 1 >
                        <xs:element ref= eitc:signalDelta
minOccurs= 0  maxOccurs= 1 />
                        <xs:element ref= eitc:signalSetpoint
minOccurs= 0  maxOccurs= 1 />
                        <xs:element ref= eitc:signalPercent
minOccurs= 0  maxOccurs= 1 />
                        <xs:element ref= eitc:programLevel
minOccurs= 0  maxOccurs= 1 />
                        <xs:element ref= emix:quantity
minOccurs= 0  maxOccurs= 1 />
                        <xs:element ref= emix:priceBase
minOccurs= 0  maxOccurs= 1 />
                        <xs:element
ref= emix:productDescription  minOccurs= 0  maxOccurs= 1 />
                          <xs:element
ref= eitc:applicationSpecificSignalBase  minOccurs= 0
maxOccurs= 1 />
                    </xs:choice>
                    <xs:element ref= emix:itemBase
minOccurs= 0  maxOccurs= 1 />
                </xs:sequence>
            </xs:extension>
        </xs:complexContent>
    </xs:complexType>
This seems to fully address Bruce's ENERGYINTEROP-504 issue on
information that needs to be filled in for SEP2 and other
application environments ?  One can use a signal stream with
application specific information,  with outbound information in an
event Stream and return information in a feedback Stream.
We've discussed the importance of this for integration and the care
and feeding of (specifically)

SEP2.
Thoughts?
Thanks!
