Those five letters are the difference between safe code and unsafe code. If you've used data-* you can rest assured your attributes will always be author-defined and not interfere with any future real attributes defined by HTML, whatever those may be. But if you invent and use invalid attributes, any browser could do something with that, any day, for any reason, and it wouldn't be a bug - you're the one that would have chosen to build on top of undocumented and non-standard behaviour. Does that sound like a reasonable approach to you when the safe and future-proof approach is so clearly marked and cheap and easy to do? |
