Element 'all' Is Invalid, Misplaced, Or Occurs Too Often

I am trying to allow the following XML pattern:

<Locales>
    <Locale Language="FR">
        <Name>La Jetée</Name>
    </Locale>
    <Locale Language="EN">
        <Name>The Jetty</Name>
    </Locale>
</Locales>

Here is the XSD I currently have, but it is giving an error about the attributes. When I remove the attributes it validates 

<xs:element name="Locales" minOccurs="0">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="Locale" maxOccurs="unbounded" minOccurs="1">
                <xs:complexType>
                    <xs:attribute name="Language" use="optional"/>
                    <xs:all>
                        <xs:element name="Name" type="xs:string" minOccurs="0"/>
                    </xs:all>
                </xs:complexType>
            </xs:element>
        </xs:sequence>
    </xs:complexType>
</xs:element>

The error I get is

Element 'all' Is Invalid, Misplaced, Or Occurs Too Often.

Your XSD is fine except that you have to move xs:all before xs:attribute; it may not appear after xs:attribute, thus the error.

Here is your XSD fragment with the above change applied:

  <xs:element name="Locales">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="Locale" maxOccurs="unbounded" minOccurs="1">
          <xs:complexType>
            <xs:all>
              <xs:element name="Name" type="xs:string" minOccurs="0"/>
            </xs:all>
            <xs:attribute name="Language" use="optional"/>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

It will successfully validate your XML. Note that it also removes minOccurs="0" because occurrence constraints may not appear on top-level elements.

First of all, you should be able to use a tool such as http://www.freeformatter.com/xsd-generator.html to infer the xsd structure that's required.

For the above case, something like the following should work:

<xs:element name="Locales">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="Locale" maxOccurs="unbounded" minOccurs="0">
        <xs:complexType>
          <xs:sequence>
            <xs:element type="xs:string" name="Name"/>
          </xs:sequence>
          <xs:attribute type="xs:string" name="Language" use="optional"/>
        </xs:complexType>
      </xs:element>
    </xs:sequence>
  </xs:complexType>
</xs:element>
