SCMS201001 Schema not specified
Problem
The content type field property cust:SchemaSetId
is not specified for the field of an item being edited.
A schema is not available and therefore schema validation and Intellisense is not available. The edited item can be saved and activated.
This error occurs when using the SXML editor in the manager to edit xml fields.
Resolution
Configure the content type field property cust:SchemaSetId
and assign it a valid schema set id.
