importing schemas with xerces 1.3.1 . what is wrong in this xml?
With xerces 1.3.1 and CR for xml schema when I imported
the standard http://www.w3.org/XML/1998/namespace for use of xml:lang,
it gets parsed perfect when I use xml spy or turbo xml but with xerces parser it gives error :
"Globally defined attributes should have use= default or fixed "
I do not have any attributes in my xml schema, so I guess it is refering to attributes defined in xml.xsd mentioned in
schemaLocation in import .
If I do not give schemaLoacation , xerces gives error :
" File "" not found."
Following is the xml snippet :
<xsd:schema xmlns:xsd = "http://www.w3.org/2000/10/XMLSchema"
elementFormDefault = "qualified">
<xsd:import namespace = "http://www.w3.org/XML/1998/namespace"
schemaLocation = "http://www.w3.org/2000/10/xml.xsd"/>
Any help is appreciated,
Komal.

Re: importing schemas with xerces 1.3.1 . what is wrong in this xml?
Posted by komal mangtani <mk...@bea.com>.
I defined a prefix ( cannot give xml as it is a reserved word) for 1998 namespace.
turbo xml gives error which is more specific though :
"Error in http://www.w3.org/2000/10/xml.xsd" . If value is present , 'use' must be one of default or prefixed."
So I guess, the problem is with what I have given in schemaLocation.
What is the valid value for schemaLocation in that case?
Also, note that xerces makes it mandatory to specify schemalocation.

Re: importing schemas with xerces 1.3.1 . what is wrong in this xml?
Posted by "David A. Riggs" <dr...@asset.com>.
I believe that if you're importing that namespace in order to use its globally defined
attributes or elements, you need to associate it with a prefix like this:
<xsd:schema xmlns:xsd = "http://www.w3.org/2000/10/XMLSchema"
xmlns:xml = "http://www.w3.org/XML/1998/namespace"
elementFormDefault = "qualified">
<xsd:import namespace = "http://www.w3.org/XML/1998/namespace"
schemaLocation = "http://www.w3.org/2000/10/xml.xsd"/>
Then you can use things in that namespace as long as you qualify them with
the prefix, like this:
<xsd:attribute ref = "xml:lang"/>
Hope that helps.
