The operator elements are used by filter elements to describe how the operator will be used to apply the filter. The operator elements are mutually exclusive and contain the same attributes. The operator elements are:
<eq> used to describe filtering using an equal operator
<neq> used to describe filtering using an not equal operator
<lt> used to describe filtering using a less than operator
<lte> used to describe filtering using a less than or equal operator
<gt> used to describe filtering using a greater than operator
<gte> used to describe filtering using a greater than or equal operator
<other> used to describe the default case filter (matches when no other filter matches)
