DOCBOOK-APPS: xerces and schema(offtopic)

[Eric Richardson <eric@milagrosoft.com>]

Hi,

I was trying to parse the po.xsd from
http://www.w3.org/TR/xmlschema-0/#po.xsd. I'm using xerses1.4.1 for
java.

usage: java sax.SAXCount (options) uri ...

options:
  -p name  Specify SAX parser by name.
  -n | -N  Turn on/off namespace [default=on]
  -v | -V  Turn on/off validation [default=off]
  -s | -S  Turn on/off Schema support [default=on]
  -f | -F  Turn on/off Schema full consraint checking  [default=off]
  -d | -D  Turn on/off deferred DOM [default=on]
  -l | -L  Turn on/off external DTD loading [default=on]
  -w       Warmup the parser before timing.
  -h       This help screen.

Here is the command I'm using.

$ java sax.SAXCount po.xsd -v
[Error] purchase-order.xsd:2:58: General Schema Error: Grammar with uri
2: http://www.w3.org/2001/XMLSchema , can not be found.
[Error] po.xsd:2:58: Element type "xsd:schema" must be declared.
......

Does anybody know what the correct url is for the following?
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

Or am I totally in left field and you can't validate an XML file that
contains schema?
