In this chapter we examine closely the XML specification and learn how to create a well-formed XML document. The relevance of each topic to ActionScript is considered, and must often be seen in the light of an evolving implementation.

Readers with a moderate experience in XML might find this chapter useful. Each time the XML specification is restated in English, a new perspective is formed. XML workers might find a tiny highlight in this formulation that rounds out their mental image - if only by raising objections.

Even busy XML experts should read those topics entitled Flash Context. These point out the differences between the XML specification and the ActionScript implementation, at the time of writing and as anticipated in the future.
