Dear Wonhee and Hendo,
After looking into this with Development and Product Management, we have the following statement.
There are limitations in what is possible to support in a conversion between an FCPX XML and a ProTools AAF. The most significant of these is retiming. AAF does not support the interchange of audio retiming, so instead of not supporting this, where possible we allow the transfer of the media, however it will play out without any timing effect applied to it in the AAF.
i.e. If you have a 10 second clip in the XML that has a 2x speed effect applied the clip will only play out for 5 seconds in the XML. On a transfer to AAF the start point for the clip will be the same in the XML and the clip will play for the correct duration of 5 seconds, but it will play at normal speed.
In the AAF we will have created the whole 10 second clip and will have produced a Warning in X2Pro advising that a retimed event has occurred a point X. The intention is that you can apply the retiming to the event in ProTools.
When retiming is applied to a compound clip in the XML currently we will error and consequently fail to create an AAF.
We have looked into various ways of coping with retiming in a compound clip and have been unfortunately unable to provide a solution that could work in all scenarios. As such the only way you can work with retiming in a compound clip is to mix-down any retimed compound clips before processing through X2Pro.
The current software when it errors will warn the operator of where it has failed in processing the XML and stop. This is not terribly helpful because generally you either have no retimed compound clips in a sequence or several. It can therefore be a painstaking process resubmitting the XML each time you have mixed down a retimed compound clip or finding them yourself in the XML.
We are therefore planning to ease this process by changing the way the X2Pro software works when processing an XML it is intended it will parse through the entire project and then produce a report not just listing the Warnings that it currently does and the first point where it would have failed but all points in the XML where it would have failed previously.

Dear Wonhee and Hendo,
I have assumed that we are looking at the same XML as you both have an issue with the retimed / compound clip r328.
The clip with reference r328 is called "Blackmagic Production Camera 4K_1_2022-08-13_1728_C0003" in your project.
In the first instance you may be able to workaround the error by either removing the retiming on r238 or mixing this clip down first and then applying it to the sequence after it has been retimed.
Please advise.
Yours Sincerely
James.
