Property	Type	Description	Required or Optional	Available Version
`attachment`	`ConnectApi.FeedItemAttachmentInput`	Specifies an attachment for the comment. Valid values are: `ContentAttachmentInput` `NewFileAttachmentInput` `LinkAttachmentInput` is not permitted for comments. Important: As of version 32.0, use the `capabilities` property.	Optional	28.0–31.0
`body`	`ConnectApi.MessageBodyInput`	Description of message body. The body can contain up to 10,000 characters and 25 mentions.

To edit this property in a comment, use `updateComment(communityId, commentId, comment)`. Editing comments is supported in version 34.0 and later. Rich text and inline images are supported in comment bodies in version 35.0 and later. Inline images in content bodies must use content document (069) image files previously uploaded to Salesforce. Entity links are supported in version 43.0 and later.	Required	28.0
`capabilities`	`ConnectApi.CommentCapabilityInput`	Specifies any capabilities for the comment, such as a file attachment.	Optional	32.0
