a null namespace

[Alan Ezust <al...@gmail.com>]

Hi Michael, thanks for the reply.

I grabbed the svn source, and I'm about to integrate that into my system.

Here is the source for the code I am working on.
http://jedit.cvs.sourceforge.net/jedit/plugins/XML/xml/completion/XsdElementDecl.java?revision=1.2&view=markup

I have another question about xsd schemas - I am trying to do "import"
another xsd stylesheet (docbook 4.4 to be precise) into my namespace.

I noticed that the xsd has no targetNamespace attribute, defined, so I
left out the namespace= attrib in the <xs:import> line too, but it
seems that when I do that, I get this error message:

svn-import.1.1: the namespace attribute 'null' of an <import> element
information item must not be the same as the targetNamespace of the
schema it exists in.

I thought that the docbook 4.4 xsd has a null namespace, and
therefore, I should be able to import this one into my own namepsace
without specifying any namespace.

What is the right way to xs:import those docbook stylesheets in xerces?

It doesn't look like your schema document specifies a target namespace in 
which case you need to use xs:include [1]. xs:import [2] is for 
referencing components from other namespaces.
