Subject: [xml-dev] The universality of "single starting point"
Hi Folks,
1. Formal grammars require that a single symbol be the starting point for all productions. For example, the starting symbol is S in this grammar:
S -> a Q a
Q -> ...
2. Structured programming tells us that every function should have a single entry point.
3. XML has a single starting point - the root element
Wow! I see this concept of a single starting point everywhere I look. Above I have provided three occurrences. Would you provide other occurrences please?
/Roger
