FCP XML Import/Export issue.

I need to export an XML from Premiere, make changes to the exported XML file and then import the modified XML back into the same project, but positional keyframe data does not seem to import from a XML into Premiere. Scaling seems to work fine, but no dice on positional keyframe data.

The simplest test I've done so far to verify this problem is to export a timeline, that has motion on a couple of still images, x/y position, 2 keyframes one at the beginning and one at the end. I then import the new XML directly back into Premiere without making any changes to it and I loose all of the motion that I applied to those images. Scaling seems to work when I do the same test.

Is there a trick I can apply to the XML file to make the positional keyframes import properly?

The motion data seems to be there when I look at the XML file in a text editor.
