What does the symbol "::=" mean in specifications?
I'm reading the XML spec, and I've come across this symbol, lovingly scattered many times through out the document:
::=
Please could you tell me what it means, thanks.

The XML specification states
The formal grammar of XML is given in this specification using a simple Extended Backus-Naur Form (EBNF) notation. Each rule in the grammar defines one symbol, in the form
symbol ::= expression
