[issue33303] ElementTree Comment text isn't escaped

[Jeffrey Kintscher]

Which characters would you escape in a processing instruction? The XML spec says not to escape '<' and '&', but doesn't say what should be escaped. It seems to me that escaping '?' when followed by '>' should be sufficient since the character sequence "?>" is the closing delimiter.
