Where to post copyright information on XSD?

Question

When placing copyright information in an XML Schema Definition (XSD), is there an official (or semi-official, generally accepted) place for this?

Based Where to add a version to an XSD schema? , there is an official attribute versionin the element xs:schema- is there something similar for copyright information?

I saw people using annotation / documentation elements (like here ) for something like this - is this a common way to do this?

<xsd:annotation>
  <xsd:documentation xml:lang="en">
     Copyright 2015 Example.com. All rights reserved.
  </xsd:documentation>
</xsd:annotation>

XSD itself does not have specific direct support for copyright information. In practice, three methods are used:

• XML level comments:

  <!-- Copyright 2015 Example.com. All rights reserved. -->
  

  , , XSD. , ​​ XML (<?xml version="1.0" encoding="utf-8" ?>), XSD, XSD .

• XSD ( ):

  <xsd:annotation>
    <xsd:documentation xml:lang="en">
      Copyright 2015 Example.com. All rights reserved.
    </xsd:documentation>
  </xsd:annotation>
  

  XML-, - : , / .

• appinfo XSD:

  <xsd:annotation>
    <xsd:appinfo>
      <copyright-notice>
        Copyright 2015 Example.com. All rights reserved.
      <copyright-notice>
