TypeId: {E361280D-01DC-431A-9823-4AFACD06418B}
ShortName: SP.Publishing.PublishingPage
The PublishingPage class provides publishing-related behavior for an ASPX page that is stored in a PublishingWeb (section 3.1.5.22).
Instantiate this class by using the static GetPublishingPage (section 3.1.5.20.2.2.1) method.
This class also directly exposes the underlying ListItem ([MS-CSOMSPT] section 3.2.5.87) through the ListItem (section 3.1.5.20.1.2.1) property, so that additional ListItem functionality can be easily accessed.
