Data Mart Dataset not visible in XMLA Workspace Endpoint

[Andrew_Tuplin]

I created a DataMart a few days ago which has data for it. When I open the XMLA endpoint for the workspace in SSMS, I can see other datasets but not the dataset created by the data mart.

Ideally, each dataset would have its own XMLA endpoint (rather than one per workspace) and the Dat Mart dataset should be accessible via XMLA endpoint.
