Error when using XJC with xml.xsd import: "Failed to read xml.xsd schema document"

I am trying to run xjc in third-party schema files (this is the Amazon.com API). Well, I have problems because with one of the default.xsd files, xjc works on the following import (it is the first immediately after the declaration of the scheme):

<import namespace="http://www.w3.org/XML/1998/namespace" schemaLocation="xml.xsd" />

I'm not an XML expert, but I thought that xml.xsd is part of the "core" XML / XSD library and that XJC will know the details of this library by default. But when I run the task, I get this error:

[WARNING] schema_reference.4: Could not read the schema document 'xml.xsd' because 1) the document could not be found; 2) the document cannot be read; 3) the root element of the document is not, line 9 of the file: / C: /temp/amazon/default.xsd

[ERROR] src-resolve: Unable to resolve the name "xml: lang" in the (n) component of the attribute attribute. line 119 File: / C: /temp/amazon/default.xsd

I tried to load the xml.xsd file from http://www.w3.org/2001/03/xml.xsd into the directory with these schema files and run the command again, but xml. xsd does not check:

[ERROR] schema_reference.4: Could not read the schema document 'file: / C: /temp/amazon/xml.xsd' because 1) the document could not be found; 2) the document cannot be read; 3) the root element of the document is missing. unknown location

I was about to start going down the rabbit hole, why this would not be verified, but decided to hold on, because I think that I have something really simple or small. Do I need to manually enable xml.xsd import, or am I missing something else?
