Named versus Numeric Entities

Filed under:

I was kindly notified that my RSS feed was ill-formed for the past few days, because of an — entity in one of my previous posts. While I have fixed manually the issue, I was asked in return why this entity made my feed invalid. I’m taking this question as an opportunity to start a new category on tutorials about markup languages; it may end up being only one article only, but I’m interested in getting more questions for this category if people find it useful (let me know through comments or mail).
