------------------------------------------

Hi Savorjava,
the schema files have two errors in it:

1) resource_lists.xsd defines this "listType" as a sequence of

      <xs:element name="display-name" type="display-nameType" minOccurs="0"/>
      <xs:sequence minOccurs="0" maxOccurs="unbounded">
        <xs:choice>
          [...]
          <xs:any namespace="##other" processContents="lax" minOccurs="0" \
maxOccurs="unbounded"/>  </xs:choice>
      </xs:sequence>
      <xs:any namespace="##other" minOccurs="0" maxOccurs="unbounded"/>

and this is ambiguous because the unbound choice contains a xs:any that is the same \
of the xs:any of the main sequence. So, in an XML like this

<display-name>...</display-name>
<entry>...</entry>
<prefix:other>...</prefix:other>

the validator doesn't know if the "prefix:other" element should be validated against \
the "<xs:any namespace="##other" processContents="lax" minOccurs="0" \
maxOccurs="unbounded"/>" or the " <xs:any namespace="##other" minOccurs="0" \
maxOccurs="unbounded"/>"

2) rls_service.xsd declares a prefix "rl" and uses it to refer to the "rl:listType" \
type, but it doesn't import the corresponding schema. There should be a

	<xs:import namespace="urn:ietf:params:xml:ns:resource-lists" \
schemaLocation="resource_lists.xsd"/>

as the first child of the xs:schema element
