' See Global Unlock Sample for sample code.

' This example will set logging properties.  The XML body of the request
' will look like this:

'         <Delete>true|false</Delete>

'         <RetentionPolicy>
'             <Enabled>true|false</Enabled>
'             <Days>number-of-days</Days>
'         </RetentionPolicy>
'     </Logging>

' Build the request:
Dim xml As New ChilkatXml
xml.Tag = "StorageServiceProperties"
