    .SYNOPSIS
        Convert the contents of an xccdf check-content element into a VsphereServiceRule object
    .DESCRIPTION
        The VsphereServiceRule class is used to extract the Vsphere Service settings
        from the check-content of the xccdf. Once a STIG rule is identified a
        Vsphere Service rule, it is passed to the VsphereServiceRule class for parsing
        and validation.
