[OASIS Issue Tracker] (ODATA-718) 5.1.2: Add example for $expand=Items/$count

[ https://issues.oasis-open.org/browse/ODATA-718?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=40546#comment-40546 ] 

Michael Pizzo commented on ODATA-718:
-------------------------------------

Rather than adding an example (which would mess up all the example numbers) I added the following descriptive text to the section:

"The $count segment can be appended to the navigation property name or type-cast segment following the navigation property name to return just the count of the related entities. The $filter and $search system query options can be used to limit the number or related entities included in the count."

We might open a separate issue to add an example in 4.1.
