      Change text to

      A property path MUST NOT appear in more than one expand item.

      Show
      Change text to A property path MUST NOT appear in more than one expand item.

      Description

      Current text on $expand in https://docs.oasis-open.org/odata/odata/v4.01/os/part2-url-conventions/odata-v4.01-os-part2-url-conventions.html#sec_SystemQueryOptionexpand says that

      A property MUST NOT appear in more than one expand item.

      This is misleading if e.g. a complex type is used multiple times.

      The option $expand=billToAddress/country,shipToAddress/country should be valid even though the country navigation property of the Address complex type appears twice, but within different property paths.
