SSAS: Weird error when Setting up Mining Structure

This is very odd; I setup a simple mining structure, and when I go to process it, I get this error. Doesn't point to the file the error is in, lists line and column as zero. Wha开发者_StackOverflow社区t would this be related to?

The ddl100_100:HoldoutMaxPercent element at line 184, column 38 (namespace http://schemas.microsoft.com/analysisservices/2008/engine/100/100) cannot appear under Envelope/Body/Execute/Command/Batch/Alter/ObjectDefinition/MiningStructure.

Thanks.

Looks like a bug being worked on:
