This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
The core test nodeprocessinginstructionsetnodevalue sets the willBeModified flag to false, however it also sets the nodeValue attribute. The problem exists in the 2/13/02 release and the version in CVS. Test implementations that use this flag for controlling caching can fail because what was suppost to be a readonly document would be modified by this test. Also DOM implementations that support a read only document would fail because a document marked as read only is modified.
