                  This attribute indicates the depth to which nested property
                  XLink linking element locator attribute (href) XLinks are
                  traversed and resolved if possible.  A value of "1" indicates
                  that one linking element locator attribute (href) Xlink
                  will be traversed and the referenced element returned if
                  possible, but nested property XLink linking element locator
                  attribute (href) XLinks in the returned element are not
                  traversed.  A value of  "*" indicates that all nested property
                  XLink linking element locator attribute (href) XLinks will be
                  traversed and the referenced elements returned if possible.
                  The range of valid values for this attribute consists of
                  positive integers plus "*".
