      <optional-params/>
      <required-params>
        <param>
          <valid-options/>
          <name>namespace</name>
          <description>Name of the domain</description>

The above instruction is not correct, parameter should be "id", not "namespace".
$ curl -k -X POST -H 'Accept: application/xml' -d namespace=jialiu --user jialiu:214214 https://ec2-107-21-165-94.compute-1.amazonaws.com/broker/rest/domains
<?xml version="1.0" encoding="UTF-8"?>
<response>
  <data>
    <datum nil="true"></datum>
  </data>
  <type nil="true"></type>
  <version>1.0</version>
  <messages>
    <message>
      <exit-code>106</exit-code>
      <field>namespace</field>
      <text>Namespace is required and cannot be blank.</text>
      <severity>error</severity>
    </message>
  </messages>
  <status>unprocessable_entity</status>
</response>


BTW, alter domain parameter should be also be updated.
$ curl -k -X GET -H 'Accept: application/xml' --user jialiu:214214 https://ec2-107-21-165-94.compute-1.amazonaws.com/broker/rest/domains
...
        <link>
          <optional-params/>
          <required-params>
            <param>
              <valid-options/>
              <name>namespace</name>
              <description>Name of the domain</description>
              <type>string</type>
            </param>
          </required-params>
          <method>PUT</method>
          <href>https://ec2-107-21-165-94.compute-1.amazonaws.com/broker/rest/domains/newjialiu</href>
