   See the XML specification: https://www.w3.org/TR/xml/#sec-comments

   This comment is not well-formed, which is why it is rejected by the XML parser used by plistlib.

   I'm closing this issue because this is IMO not a bug in plistlib, but malformed input.

   To close the loop, the relevant portion of the document is:

   For compatibility, the string " -- " (double-hyphen) must not occur within comments.] Parameter entity references must not be recognized within comments.

   for compatibility: [Definition: Marks a sentence describing a feature of XML included solely to ensure that XML remains compatible with SGML.]

   Note that Apple's plist parser does permit such comments, so this may be a source of future issues if neither system changes. I have filed a radar with Apple.
