+.It Sy projectused Ns @ Ns Em project
+The amount of space consumed by the specified project in this dataset. Project
+is identified via the project identifier (ID) that is object-based numeral
+attribute. An object can inherit the project ID from its parent object (if the
+parent has the flag of inherit project ID that can be set and changed via
+.Nm chattr Fl /+P
+or
+.Nm zfs project Fl s )
+when being created. The privileged user can set and change object's project
+ID via

+anytime. Space is charged to the project of each file, as displayed by

+The

+is similar to
+.Sy projectused
+but instead it counts the number of objects consumed by project. When the
+property
+.Sy xattr=on
+is set on a fileset, ZFS will create additional objects per-file to store
+extended attributes. These additional objects are reflected in the
+.Sy projectobjused
+value and are counted against the project's
+.Sy projectobjquota .
+When a filesystem is configured to use
+.Sy xattr=sa
+no additional internal objects are required. See the
