I would like to keep a change history in my .ui file. I started doing it by using the <comment> element but it seems to be limited to a total length of about 256 characters, and apparently only one <comment> is allowed. If I exceed these limits then I get the message "File ... is not valid" from UIC and "The file ... is not a valid Designer ui file" from Designer. If I use an XML comment (<!-- ... -->) then the file is read OK but if I modify it in Designer then the XML comment is lost upon saving.

Is there a mechanism for including long comments in ui files? Is there some other mechanism for maintaining a change history (apart from CVS, separate log file, etc.)?
