Assigns values to one or more of the attributes of a specified instance. This operation is applicable only to Explicit attributes, not to Inverse or Derive attributes. The attributes are identified by their attributeIds. Related functions: edmiRemotePutAttrs, edmiRemotePutAttrsBN, edmiRemotePutAttrsBNEx
