Re: xerces and schema(offtopic)


Sadly I'm posting to myself. Here's a solution.
Add the following to the top of the schema file.

<?xml version="1.0"?>
<!DOCTYPE xsd:schema PUBLIC "-//W3C//DTD XMLSCHEMA 200102//EN"
  "http://www.w3.org/2001/XMLSchema.dtd"; [
  <!ENTITY % p 'xsd:'><!-- overriden, default namespace is xs --> 
  <!ENTITY % s ':xsd'> 
]>

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>

...

$ xerces.sh po.xsd -v
po.xsd: 2864 ms (37 elems, 61 attrs, 1061 spaces, 145 chars)

This will validate. BTW xerces.sh is just a shell script that add
the
xerces.jar and xercesSamples.jar to the classpath and calls java
sax.SAXCount. Other ideas welcome.
