Ok, so I'm getting ready to write a service to keep the inventory up to date because we sell from multiple channels and the first thing I see that's important is that TrackInventoryBySizeAndColor is important.

I've already created products on the site using WSI with no problems, but I wasn't setting this field. So, I go to look at the specs to find out how to set this field and all it says for the field is:

<InventoryType>
<TrackInventoryBySizeAndColor></TrackInventoryBySizeAndColor>
<WarehouseLocation></WarehouseLocation>
</InventoryType>

All well and good... but how do I turn it on? Is it a boolean field?

Other fields that are boolean are shown like this:

<IsFeatured>boolean</IsFeatured>

Any answers?
