In attempting to parse embeds.xml the parser failed due to syntax.  Specifically, the xsi:schemaAttribute is being set on the Ui element without setting the xmlns:xsi attribute on it.

Correct example:
<Ui xmlns="http://www.blizzard.com/wow/ui/"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.blizzard.com/wow/ui/
..\FrameXML\UI.xsd";>
<!-- stuff here -->
</Ui>

Incorrect from AuctionLite:
<Ui xsi:schemaLocation="http://www.blizzard.com/wow/ui/
..\FrameXML\UI.xsd";>
<!-- stuff here -->
</Ui>

Not a big deal, but I thought the author would like to know.  I happened to be parsing embeds, etc. because I run disembedded and would like to know what mods are including what libraries.  This way if I remove the only mod using a certain lib, I can remove the lib as well if the Curse client doesn't automatically do it.
