in WadlConsole when -i , -o and -n is not provided , the error message is really unhelpful

I pretended to be a first timer using wadl# and wadl-sharp utility

I tried running ./wadl-sharp and was greeted with
wadl-sharp: There is one or more failed validations.
Try `wadl-sharp --help' for more information.

I tried wadl-sharp --help and got many options. All options are not necessary. So instead of "wadl-sharp: There is one or more failed validations." the utility should tell which mandatory option is missing.

Like, when I use
./wadl-sharp -i file.xml

The error message I should get something like this
ERROR:
Output file is not specified. Please use the -o option
Namespace is not specified. Please use the -n option
