[Xml-compile] Regarding SOAP 1.2 faultNotImplemented handling

[Sheeju Alex]

Hi Mark,

     Thanks mark for looking at this after you holidays, adding
`addPrefixes` code worked and I reverted to keep XC_DAEMON_NS, please see
below for details.

Yes addPrefix worked and here is the code I added to calculator.psgi

my $wsdl = XML::Compile::WSDL11->new($wsdl_filename);
$wsdl->addPrefixes(xcd => XC_DAEMON_NS);

I have another issue with fault response when an method is not implemented
I get `faultNoAnswerProduced`. Here is the code I added to fix this issue,
please let me know if there is any other better way to handle this.
