<xsd:documentation>An indicator of where the tag is attached to the item.
This is used to assist the user in finding where an identifier is
located on an item. This optional field also helps to differentiate
where an identifier is located when multiple identifiers exist on an
item. Most downhole components have a box (female thread) and pin (male
thread) end as well as a pipe body in between the ends.
Where multiple identifiers are used on an item, it is convenient to have
a reference as to which end, or somewhere in the middle, an identifier may
be closer to. Some items may have an identifier on a non-standard location,
such as on the arm of a hole opener. 'other', by exclusion, tells a user to
look elsewhere than on the body or near the ends of an item. Most
non-downhole tools will use either 'body', 'other' or not specified
as the location tends to lose value with smaller or non threaded items.</xsd:documentation>
