Official docs for the XML content escaping?

Question

I'm looking for docs on the "official" way to escape stuff in XML. Like the full list of the "<" constructs (whatever they are called) and how to use them.

---

I'm not asking for how to do it, just the official docs (or a good, reliable and correct tutorial).

Answer 1

They're called "entities": see for example this List of XML and HTML character entity references.

Answer 2

http://www.w3.org/TR/REC-xml/#syntax, third paragraph.

Answer 3

If you're going to be doing a lot of detailed work with XML, the annotated XML spec is both authoritative and insightful. It's like the DVD commentary for the XML spec!
