The keywords for this document. This key is optional. If the value of  this key is a <doc://com.apple.documentation/documentation/CoreFoundation/CFString> object, the `/Keywords` entry will be the specified  string. If the value of this key is a <doc://com.apple.documentation/documentation/CoreFoundation/CFArray> object, then it must be an array  of <doc://com.apple.documentation/documentation/CoreFoundation/CFString> objects. The `/Keywords` entry will, in this case, be the concatenation  of the specified strings separated by commas (`","`). In addition, an  entry with the key `"/AAPL:Keywords"` is stored in the document  information dictionary; its value is an array consisting of each of the  specified strings. The value of this key must be in one of the above  forms; otherwise, this key is ignored.
