A context-sensitive container tag that lists all of the pings sent to a particular entry, category or blog. If used in an entry context the tagset will list all pings for the entry. Likewise for a TrackBack-enabled category in context. If not in an entry or category context, a blog context is assumed and all associated pings are listed.
category: This attribute creates a specific category context regardless of its placement.
lastn: Display the last N pings in context. N is a positive integer.
sort_order: Specifies the sort order. Recognized values are “ascend” (default) and “descend.”
