* This example assumes the Chilkat HTTP API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* Also see Chilkat's Online WSDL Code Generator

loHttp = CreateObject('Chilkat.Http')

* We are sending the following POST:

* POST /wsdvs HTTP/1.1
* Host: peppol.helger.com
* Content-Type: application/soap+xml; charset=utf-8
* Content-Length: <length>
* 
* <?xml version="1.0"?>
* <S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
* <S:Body>
* <validateRequestInput xmlns="http://peppol.helger.com/ws/documentvalidationservice/201701/" VESID="eu.peppol.bis2:t10:3.3.0" displayLocale="en">
* <XML>...ENTITY_ENCODED_INVOICE_XML_GOES_HERE...</XML>
* </validateRequestInput>
* </S:Body>
* </S:Envelope>

* Build the SOAP XML shown above.
* First load the PEPPOL invoice that will be the data contained in the <XML>...</XML> SOAP element.
* We are using the XML invoice obtained from https://github.com/austriapro/ebinterface-standards/blob/master/schemas/ebInterface5p0/samples/ebinterface_5p0_sample_ecosio.xml
