[oXygen-user] XSD, catalog and PUBLIC IDs

[Theun Fleer]

hi Sorin and Eliot

thank for your respones!

So, I changed my @xsi:schemaLocation to an URI

<?xml version="1.0" encoding="US-ASCII"?>
<be
xsi:noNamespaceSchemaLocation="http://www.daidalos/nl/puma/be-jur-off.xs
d" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
...
</be>

> If you are using the Xerxes parser (which is what Oxygen uses by
default), in your catalog, use

is because Xerces implements

and I changed my catalog to 

<system systemId="http://wwww.daidalos.nl/puma/be-jur-off.xsd"
uri="be-jur-off/be-jur-off.xsd"/>
<system systemId="http://wwww.daidalos.nl/puma/be-jur-com.xsd"
uri="be-jur-com/be-jur-com.xsd"/>

for Xerces and

<uri name="http://wwww.kluwer.nl/puma/be-jur-off.xsd"
uri="be-jur-off/be-jur-off.xsd"/>
<uri name="http://wwww.kluwer.nl/puma/be-jur-com.xsd"
uri="be-jur-com/be-jur-com.xsd"/>

for other parsers

and in oXygen / Xerxes it works like a charm; catalog is resolved and
validation is OK.  
I will have to do some testing for others parsers we use in the project.


Thanks again!
