+This patch makes the UUIDs in the XMP header optional, depending on the
+setting of the environment variable GS_GENERATE_UUIDS.
+
+If the environment variable GS_GENERATE_UUIDS is set to "0" or "no", it will
+not write out the Document UUID field and also will write the Instance ID
+field value as "".
+
+Upstream does not want to do this.
