Hi,

I am trying to compile a schema from the OASIS document format DITA that
can be found here:
http://docs.oasis-open.org/dita/v1.1/CS01/schema/ditaschema.zip

Unfortunately, I get an error even if I use the simple binding mode
described here:
http://weblogs.java.net/blog/kohsuke/archive/2006/03/simple_and_bett.html

C:\JAXB\jaxb-ri-20090206\bin>xjc -extension simpleMode.xsd
c:\JAXB\ditaschema\topic.xsd
parsing a schema...
[ERROR] Property "Alt" is already defined. Use &lt;jaxb:property> to

[ERROR] The following location is relevant to the above error
  line 1566 of file:/C:/JAXB/ditaschema/commonElementMod.xsd

Failed to parse a schema.


Without the simple binding mode, I get even more errors:

Is there anything else I can do to compile the schema?

Thanks for any help,

M.S.
