Working with SOAP WebServices with dynamic typing

[SDorogin]

Given WSDL/XSD schema:

<xsd:complexType name="ArrayOfKeyValueOfstringanyType">
  <xsd:sequence>
    <xsd:element minOccurs="0" maxOccurs="unbounded"
           name="KeyValueOfstringanyType">
      <xsd:complexType>
        <xsd:sequence>
          <xsd:element name="Key" nillable="true" type="xsd:string"/>
          <xsd:element name="Value" nillable="true" type="xsd:anyType"/>
        </xsd:sequence>
      </xsd:complexType>
    </xsd:element>
  </xsd:sequence>
</xsd:complexType>

And some WSDL/SOAP WebService response with such an object property:

<Properties xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<a:KeyValueOfstringanyType>
  <a:Key>Name</a:Key>
  <a:Value i:type="b:string" xmlns:b="http://www.w3.org/2001/XMLSchema">Тестовый отдел 19</a:Value>
</a:KeyValueOfstringanyType>
<a:KeyValueOfstringanyType>
  <a:Key>Parent</a:Key>
  <a:Value i:type="b:string" xmlns:b="http://www.w3.org/2001/XMLSchema">88b4e90c-b9fb-4e30-b180-062e68204b11</a:Value>
</a:KeyValueOfstringanyType>
</Properties>

DataSource transforms this XML with given XSD-schema into such JS-code:

Properties:{
	'xmlns:a':"http://schemas.microsoft.com/2003/10/Serialization/Arrays", 
	KeyValueOfstringanyType:[
		{
			Key:"Name", 
			Value: {
				'i:type': "b:string", 
				'xmlns:b': "http://www.w3.org/2001/XMLSchema", 
				xmlTextContent: "some text value"
			}
		}, 
		{
			Key:"Parent", 
			Value: {
				'i:nil': "true"
			}
		}
	]
}

This result is pretty straightforward mapping between xml/xsd and JS. I'm not going to say it's incorrent.
But Value element has standard typing attribute in standard W3C schema ("http://www.w3.org/2001/XMLSchema").
Wouldn't it be a good idea to create just:

{Key: "Name", Value: "some text value"}

(without any nested properties) ?

It turns out that working with SOAP WebServices which returns data with dynamic typing (value _and_ its type in "http://www.w3.org/2001/XMLSchema" schema) is almost impossible.
I have to write transforResponse method for WS-based DataSource and parse all cases into some simple structure like [{"Name": "some text value", "Parent": null}]. It's a pain.

So treat this please as a feature request. And what are my options right now except parsing all XSD types on my own?
