XML::SAX::DocumentLocator - Helper class for document locators

       There is only 1 method: "new". Simply pass it a list of closures that when called will return the
       PublicId, the SystemId, the LineNumber, the ColumnNumber, the Encoding and the XMLVersion respectively.

       The closures are passed a single parameter, the key being requested. But you're free to ignore that.

       This module gives you a tied hash reference that calls the specified closures when asked for PublicId,
       SystemId, LineNumber and ColumnNumber.

       It is useful for writing SAX Parsers so that you don't have to constantly update the line numbers in a
       hash reference on the object you pass to set_document_locator(). See the source code for
       XML::SAX::PurePerl for a usage example.
