Specify the data type and other attributes of the new property.
To add a new Endeca property:
Endeca properties and dimensions share a namespace in the Endeca MDEX Engine. For this reason, all Endeca property and dimension names must be unique. If the application will use Endeca Query Language requests, all property and dimension names must be in an NCName format. For more information about the Endeca Query Language and the NCName requirement, see the Endeca Advanced Development Guide.
