Notas
To get UserDefinedType object permissions, users can be a member of the public fixed server role.
To set UserDefinedType object permissions, users must have CREATE TYPE permission in the parent database and ALTER permission on specified schema. If an assembly is specified, users must either own the assembly or have REFERENCES permission on it.
To create a alias data type, users must have CREATE TYPE permission in the parent database and ALTER permission on specified schema. If an assembly is specified, users must either own the assembly or have REFERENCES permission on it.
To drop a alias data type, users must have CONTROL permission on the type and ALTER permission on the specified schema.
