Baseline field XML schema discrepancy between 2003 and 2007

[GymT]

If you have BaselineN fields populated in MSP 2007 and save the project to an
..xml file, the <Baseline> fields are not stored the same as MSP 2003 .xml.

I can understand if there was a change to the schema for MSP 2007, but there
does not appear to be any changes as to how <Baseline> fields are stored in
the .xml file format.

Also, if you open the .xml file saved in MSP 2007 in MSP 2007, the BaselineN
field values are lost?

This is what MSP 2003 looks like when save to .xml file format:
<Task>
...
<Baseline>
<Number>1</Number>
<Cost>25000</Cost>
</Baseline>
<Baseline>
<Number>2</Number>
<Cost>27500</Cost>
</Baseline>
</Task>

This is what MSP 2007 looks like when save to .xml file format:
<Task>
...
<Baseline>
<Number>1</Number>
<Cost>25000</Cost>
<Cost>27500</Cost>
</Baseline>
</Task>

I have installed the latest Serice Packs for WindowsXP, Office, and Project.

I would like to know if this is a known issue and of any possible workarounds.

Regards.
