No, there's no difference. This has been carried through as a limited means of presenting attribute values that
contain quotation marks as data characters. For instance, you might use:
  <foo bar="you're it">
  <foo bar='she said "fire", I think'>
but still not
  <foo bar="she said "you're it", I think">
  <foo bar='she said "you're it", I think'>
as the first occurrence of a quotation mark that matches the opening one delimits the attribute value.

The rule is - be careful...
