XML-RPC Client and Server

The `xmlrpc` package provides a pure JavaScript implementation of an XML-RPC client and server for Node.js environments. Its core differentiator is the exclusive use of JavaScript libraries for XML parsing (via `sax-js`) and XML building (via `xmlbuilder`), thereby avoiding native C dependencies and their associated build requirements. This allows developers to set up XML-RPC communication without needing a C compiler or specific system libraries. The package supports both client and server roles, enabling applications to make and receive XML-RPC method calls. Key features include configurable ISO 8601 date/time formatting for both encoding and decoding, and optional support for HTTP cookies to maintain session state. The latest stable version is 1.3.2, released in June 2016. Due to its age, it exhibits an effectively abandoned release cadence, with no updates in nearly a decade.
