    .PARAMETER ADOM
    The (non-default) ADOM for the requests.

    The new address, generated e.g. by using New-FMObjAddress or Get-FMAddress
 
      .PARAMETER EnableException
    Should Exceptions been thrown?
 
    .EXAMPLE
    $testAddress=Get-FMAddress -filter "name -eq MyDUMMY" -verbose
    $testAddress.comment="Modified at $(Get-Date)"
    $testAddress | Update-fmaddress
 
    Sets the comment field (must exist or you need to have e.g. Add-Member.)
 
    .EXAMPLE
    $testAddress=Get-FMAddress -filter "name -eq MyDUMMY" -verbose
    $testAddress.name="MyDUMMY 2"
    Update-fmaddress -Address $testAddress -Name "MyDUMMY"
 
    Renames the address "MyDUMMY" to "MyDUMMY 2"
 
    .EXAMPLE
    Update-fmaddress -Address @{name="MyDUMMY 2"} -Name "MyDUMMY"
 
    Renames the address "MyDUMMY" to "MyDUMMY 2", everything else will be kept unchanged.
 
    .NOTES
    If an address object does not contain every attribute which is already set,
    then the existing values will be kept.
