are these two XML`s the same?

i am currently writing a web service client in delphi 7 (service itself is in c#). everything seems to be working just fine. when i run a fiddler to look how does the xml going from my client app looks like i noticed that is looks different when i write the "same" client app in c#. Below are two xml`s

one that goes from a Delphi 7 app

<?xml version="1.0"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
  <SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:NS2="http://tempuri.org/">
    <NS1:SomeTagName xmlns:NS1="http://tempuri.org/">
      <SomeID xsi:type="xsd:int">12345</SomeID>
      <SomeStatus xsi:type="NS2:SomeStatusType">SOME_OK_STATUS</SomeStatus>
    </NS1:SomeTagName>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

one that goes from c# app

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Body>
    <SomeTagName xmlns="http://tempuri.org/">
      <SomeID>12345</SomeID>
      <SomeStatus>SOME_OK_STATUS</SomeStatus>
    </SomeTagName>
  </s:Body>
</s:Envelope>

i am not fluent in xml so i did some research and to this moment i am able to tell that

1. UTF-8 is the default for documents without encoding information - ref. here - that means no difference here


2. XML Namespaces provide a method to avoid element name conflicts - ref. here - namespaces are different (s: and SOAP-ENV:) but there are specified, and as far as i am concerned should not make the difference either

but what about the schema - not sure about that. There are some extra attributes in the Envelope or datatypes in SomeID and SomeStatus tags. But that came from service wsdl (i quess?!).

Final questions:

1. Why the app written in c# (vs2012) does not add all the extra schema information to the xml. Does it really matter if the xml has them or not?


2. can anyone tell if these can be considered as the same?
