SRU::Request::Explain - A class for representing SRU explain requests

    ## 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.
