	26	<xsd:documentation>The root container for all WITSML data.
	27	This schema is not designed for use with the WITSML API.
	28	Rather it captures the logical model represented by the API queriable objects.
	29	As such it can represent all data in a server or it can represent data outside the context of a server.
	30	The data in the API objects have been incorporated into a normal XML hierarchy of well/wellbore.
	31	The plural API root elements have essentially been renamed to "xxxSet".
	32	The content of the well and wellbore API objects has been captured in "generalInformation" elements.
	33	The realtime object is not included because it is considered to be a transient server concept.
	34	The trajectoryStation object is not included because it is redundant to the data in trajectory.
