[XML-SIG] raising exceptions in dom.core

[Jeff.Johnson@icn.siemens.com]

The following code shows two class based exceptions but in the first, the
message is passed along as an argument to 'raise' while in the second, the
message is given in the constructor of the exception.  Should this be changed to
use the constructor in both cases?


        if self.readonly:
            raise NoModificationAllowedException, "Read-only node "+repr(self)
        self._checkChild(newChild, self)

        if newChild._document != self._document:
            raise WrongDocumentException("newChild %s created from a "
                                         "different document" %
(repr(newChild),) )
