Attached is a proposal for the schema to be used in the scenarios. The pseudo-schema would change to the following to match this:

<sce:Animal ...>
  <sce:ID> UUID </sce:ID>
  <sce:Name> xs:string </sce:Name> ?
  <sce:Birthdate> xs:date </sce:Birthdate> ?
  <sce:DateTagged> xs:date </sce:DateTagged>
  <sce:Gender> xs:string </sce:Gender>
  <sce:Family> xs:string </sce:Family>
  <sce:Genus> xs:string </sce:Genus>
  <sce:Species> xs:string </sce:Species>
  <sce:Location> gpx:ptType </sce:Location>
  <sce:EPR> wsa:endpoint-reference to this Animal </sce:EPR> ?
  xs:any
</sce:Animal>

If people are OK with this, I'd like to add it to the scenario doc.
