WDS client unattend.xml problem

I have a hard disk which is about 150GB and I want to create two partitions on it. The following script shows how I did that, but it does not work. I got an error something like "error parsing DiskConfiguration". Could anyone help me out? thx

<DiskConfiguration>
   <Disk>
      <DiskID>0</DiskID>
      <WillWipeDisk>true</WillWipeDisk>
      <CreatePartitions>
           <CreatePartition>
<!-- Create primary partition, 50GB --!>
                 <Order>1</Order>
                 <Type>Primary</Type>
                 <Size>50000</Size>
           </CreatePartition>
<!-- Create extended partition and fill the rest of the hard disk --!>
           <CreatePartition>
                <Order>2</Order>
                <Type>Extended</Type>
                <Extended>true</Extended>
           </CreatePartition>
<!-- Create logical partition within the extended partition --!>
          <CreatePartition>
                <Order>2</Order>
                <Type>Logical</Type>
                <Extended>true</Extended>
           </CreatePartition>
      <CreatePartitions>
      <ModifyPartitions>
           <ModifyPartition>
                <Order>1</Order>
                <PartitionID>1</PartitionID>
                <Letter>C</Letter>
                <Format>NTFS</Format>
               <Active>true</Active>
           </ModifyPartition>
          <ModifyPartition>
                <Order>2</Order>
                <PartitionID>2</PartitionID>
