<xs:element name="SchemaMaster" nillable="true" type="xs:string" />
The SchemaMaster element is populated from the server!dnsHostName attribute on the parent of the Schema Master's nTDSDSA object. The Schema Master's nTDSDSA object is the object referenced by the dMD!fSMORoleOwner attribute on the schema NC root. See [MS-ADTS] section 220.127.116.11.18.104.22.168.1 for information on the nTDSDSA object. See [MS-ADTS] sections 22.214.171.124.11 and 6.1 for information on FSMO roles and the fSMORoleOwner attribute. If the dMD!fSMORoleOwner or server!dnsHostName attribute is not present or cannot be read due to the client lacking access rights to read the attribute, the server returns a null ActiveDirectoryForest/SchemaMaster element.
