In a file with XMP metadata each one set or cleared is also set or removed as pdfx:<name> (the http://ns.adobe.com/pdfx/1.3/ schema, where Acrobat keeps them), so tools that read XMP see the same properties; a name that can't be an XML element name (1st, Q&A, a:b) stays in /Info only. In a file that declares PDF/A one the packet already has is changed or removed, but none is added, since PDF/A-1 to -3 allow a schema only when the packet describes it (ISO 19005-2 §6.6.2.3); a packet that binds the pdfx prefix to another namespace is left alone. Not yet: an XMP packet for a file without one, and reading custom properties a file states only in XMP"
