leaves the service. Bi-directional states that data flows both ways, and unknown
states that the direction is not known.</xs:documentation>

<xs:documentation>The version allows component publishers/authors to make changes to existing
BOMs to update various aspects of the document such as description or licenses. When a system
is presented with multiple BOMs for the same component, the system should use the most recent
version of the BOM. The default version is '1' and should be incremented for each version of the
BOM that is published. Each version of a component should have a unique BOM and if no changes are
made to the BOMs, then each BOM will have a version of '1'.</xs:documentation>
