Problems with fdi file syntax

[Kevin Oberman]

I am trying to create an FDI file to prevent a partition from
mounting, but I get the error:
error in FDI file
/usr/local/share/hal/fdi/preprobe/20thirdparty/10-ignore-ufs-extras.fdi:6:
not well-formed (invalid token)

The line is (as far as I can tell) identical to the example in the HAL FAQ.

Here is the file in question:
<?xml version="1.0" encoding="UTF-8"?>

<deviceinfo version="0.2">
  <device>
    <match key="block.device" string="/dev/ntfs/SYSTEM_DRV"
      <merge key="info.ignore" type="bool">true</merge>
    </match>
  </device>
</deviceinfo>

Any idea what dumb mistake I am making.
