keywords
The keywords of the attachment concatenated as a string. Despite its plural inflection, this property is typically treated as a single keyword.
Multiple keywords can be concatenated into the string using a delimiter (for example, a comma) if desired but other APIs, like AttachmentsPopupElement, will treat the entire string as a single keyword and additional custom parsing will be required to split the string into multiple keywords.
