this is erroring out:

<Query xmlns=" [http://clarizen.com/api](http://clarizen.com/api)" xmlns:xsi=" [http://www.w3.org/2001/XMLSchema-instance](http://www.w3.org/2001/XMLSchema-instance)">

<queryExpression xmlns:q1=" [http://clarizen.com/api/queries](http://clarizen.com/api/queries)" xsi:type="q1:EntityQuery">

<q1:Paging xsi:nil="true" />

q1:Fields<string>Phase</string>

<string>Project</string><string>LastUpdatedOn</string>/q1:Fields

<q1:Orders xsi:nil="true" />

q1:TypeNameProject/q1:TypeName

<q1:Where xsi:type="q1:Compare">

------------------- 

If I take out the xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance" it is fine (but my xml parser accept only correctly specified xmls) 

so whith this the query is ok: <Query xmlns=" [http://clarizen.com/api](http://clarizen.com/api)"> 

but in this case the xsi is not specified!
