I believe..

1) It is an error to specify an external subset when you mention
standalone="yes" -- I think it is an error which should be reported even
if it is non-validating parser.

2) When stand-alone is no, a non-validating parser is not required to read
external declarations. I believe that it is not supposed to check even
whether the URI is valid.. I believe a non-validating parser need not
report an error.

Again, I am *not* sure of the above. If someone can verify, that will be
great.

thanks and regards - murali.
