  11                         A <ref target="ore:Proxy">Proxy</ref> representing a single item in an <ptr target="olo:OrderedList">Ordered List</ptr>.

  14                         Slots are required to have an <ref target="olo:index">index</ref>, which should be less than or equal to its <ref target="olo:ordered_list">ordered list</ref>¦s <ref target="olo:length">length</ref>, and an <ref target="olo:item">item</ref>, providing the thing being proxied by the slot.

  16                 <p>
  17                         A Slot is not actually required to have an ordered list by <ptr target="(OLO)"/>, and this caveat may prove useful for ordered slots in <ref target="ore:Aggregation">Aggregations</ref> of indeterminate length, or Aggregations which allow multiple slots with identical indices.
  18                         In these cases, Slots will still never·the·less <ref target="ore:proxyIn">be a proxy in</ref> some Aggregation, which provides the context for interpreting their index.
