154908 - Moving content nodes between documents does not preserve uniquenes of content IDs

Status: RESOLVED WORKSFORME

(Core :: DOM: Core & HTML, defect)

Description

[Simon Fraser [no longer active]]

If you write code that creates content nodes on document A:

docA->CreateElementNS(..., &newElement);

then appends them to document B:

nodeInDocB->AppendChild(newElement, ..);

then it's possible to get content node ID conflicts.

It would seem that copying or moving nodes between documents should ensure that
content IDs (gotten via GetContentID() remain unique for each document. If a
node is in 2 documents at the same time, then, I guess, it would have to have an
ID per document.

Content ID's are evil. If at all possible we should work on removing them in
stead of making them...

Looks like they were removed at some point.
