Subclass of [ConnectApi.FeedElementCapability](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_connectapi_output_feed_element_capability.htm "A feed element capability, which defines the characteristics of a feed element."). For files attached to a feed post (instead of a comment) in version 36.0 and later, use [ConnectApi.FilesCapability](https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_connectapi_output_multiple_content_capability.htm "If a feed element has this capability, it has one or more file attachments."). If content is deleted from a feed element after it’s posted or if the access to the content is changed to private, the ConnectApi.ContentCapability exists, however most of its properties are null.
