Advantages of XML Events
XML Events uses a separation of concerns design pattern, and is technology-neutral with regard to handlers. It gives authors freedom in organizing their code and allows separation of document content from scripting.
Legacy HTML and early SVG versions bind events to presentation elements by encoding the event name in an attribute name, such that the value of the attribute is the action for that event at that element. For example (with Javascript’s onclick attribute):
Stay here!
This design has three drawbacks:
- it hard-wires the events into the language, so that adding new event types requires changes to the language
- it forces authors to mix the content of the document with the specifications of the scripting and event handling, rather than allowing them to separate them.
- it restricts authors to a single scripting language per document.
