Consider adding support for offline capability installs.

current:

WindowsCapability [String] #ResourceName                                                                                                                                                                                                               {                                                                                                                                                                                                                                                          Name = [string]
    [DependsOn = [string[]]]
    [Ensure = [string]{ Absent | Present }]
    [LogLevel = [string]{ Errors | Warnings | WarningsInfo }]
    [LogPath = [string]]
    [PsDscRunAsCredential = [PSCredential]]
}

proposed:

WindowsCapability [String] #ResourceName                                                                                                                                                                                                               {                                                                                                                                                                                                                                                          Name = [string]
    [DependsOn = [string[]]]
    [Ensure = [string]{ Absent | Present }]
    [LogLevel = [string]{ Errors | Warnings | WarningsInfo }]
    [LogPath = [string]]
    [PsDscRunAsCredential = [PSCredential]]
    [Source =  [string]]
}
