Even I am not sure why/how using a system identifier works as it does :
I am cc'ing David Baron in the hopes that he can clarify the
underlying mechanism.

David, could you please let Olivier and I know why/how using a SYSTEM
identifier causes Mozilla to use Full Standards Mode ?

This question arose because my use of a SYSTEM doctype causes the
validator to be unsure whether to use SGML or XML rules for parsing ...

I'll revert to a PUBLIC doctype for now, as the warning will
undoubtedly confuse my webmasters, none of whom are professionals.
