Org.OData.Core.V1 defines Term IsURL but references it as IsUrl

Term IsURL is defined as:

<Term Name="IsURL" Type="Core.Tag" DefaultValue="true" AppliesTo="Property Term">
<Annotation Term="Core.Description" String="Properties and terms annotated with this term MUST contain a valid URL" />
<Annotation Term="Core.RequiresType" String="Edm.String" />
</Term>

but it is referenced with the incorrect case as 'IsUrl':

<Term Name="ResourcePath" Type="Edm.String" AppliesTo="EntitySet Singleton ActionImport FunctionImport">
<Annotation Term="Core.Description"
String="Resource path for entity container child, can be relative to xml:base and the request URL" />
<Annotation Term="Core.IsUrl" />
</Term>

The CSDL doesn't seem to refer to case-sensitivity, but note the precedent set by:
