XMLSerializer Deserialization - array element order

We are using XMLSerializer.Deserialize(XMLReader) on .Net 4.5 to deserialize XML into an Object Graph generated by xsd.exe.

I would like to know what the expected deserialization behavior is for an array which is annotated with the XMLElementAttribute - specifically with regard to ordering. For example:

For the following property:

[System.Xml.Serialization.XmlElementAttribute("GivenName")]
  public string[] GivenName {
 // get() and set() methods
}

And the following XML:

<root>
  <GivenName>One</GivenName>
  <GivenName>Two</GivenName>
  <GivenName>Three</GivenName>
</root>

Will this always deserialize as ['One', 'Two', 'Three']

So that the array order always matches the XML order

Also is there any documentation I can reference that clearly states this.

Thanks
