Dear venerable Monks, I am seeking wisdom about Moose Object attribute. Well I would like to know if there exists a way to define an attribute that refers to an Object, in particular an XML::Simple object. I did something like that :

 has 'xml' =>(is=>rw, isa=>'XML::Simple').

And then I set the xml attribute as this 

 sub set_xml{
       (my $self, my $xml)=@_;
       $self->xml($xml);

}

But each time I call this method I obtain the following error : Attribute (xml) does not pass the type constraint because: Validation failed for 'XML::Simple' with value HASH(0x3775688). I can't get rid of this error . Thanks In advance.
