## creating a new request my $request = SRU::Request::Explain->new();
SRU::Request::Explain is a class for representing SRU 'explain' requests. Explain requests essentially ask the server to describe its services.
The constructor, which you can pass the optional parameters parameters: version, recordPacking, stylesheet, and extraRequestData parameters.
my $request = SRU::Request::Explain->new( version => '1.1', stylesheet => 'http://www.example.com/styles/mystyle.xslt' );
Normally you'll probably want to use the factory SRU::Response::newFromURI to create requests, instead of calling new() yourself.
