I was thinking that: in the quotes you MUST escape the ", and you MAY
escape the others.

Exactly.
So, in the interest of clarity, here's the core problem:
If one allows unescaped " in quoted values, this causes ambiguities:
[alt text](/url/ "Title with ") quote and parens inside ")
there are 2 ways to interpret this fragment. Such things should not happen.
Or consider also:
[alt text](/url/ "Title with ") [alt text](/url/ "quote and
parens inside ")
how to interpret this? The grammar is ambiguous.
I don't know much about parsing, but can you actually build a parser
for this grammar? (any CS person out there?)
IMHO it was not a good idea to allow such construct.
The standard pattern in many languages is to allow single and double
quotes, so if you have a title with many single quotes, you use the
double quotes, and viceversa:
"bah 'bah' bah" = "bah \'bah\' bah" = 'bah \'bah\' bah'
'bah "bah" bah' = 'bah \"bah\" bah' = "bah \"bah\" bah"
This should be enough for all needs.
p.s.
Happy new year!
