Right. Note also that 1.6 will also avoid duplicates at label _creation_ or when portion of text is copied&paste. But LyX won't touch the labels of an open document without intervation from the user.

Side note FYI: In 1.6 duplicate Labels are not changed automatically but they are clearly marked as DUPLICATE in the work area and in the new Navigator (former outline pane). So it's easy to spot where the problems lie in the document. Also worth of note is that 1.6 won't allow the creation of duplicate labels, it will automatically rename the duplicate label. Another interesting feature is that broken are marked as BROKEN. Abdel.
Re: Discussion: Labels and parent-child documents
Well, one problem I can see is that this could make cut and paste between documents difficult. And it involves a lot of keeping track of what's a child of what. Not really. Note that labels and cross-references are only updated when we export to latex. But maybe something like this could be made to work. You're welcome to bugzilla it. I just wanted to see what people thought about it before opening a file in bugzilla. But it seems most people do not have an opinion on this :-) I will report it now on bugzilla. rh

Imagine we are working in document A and want to insert a reference to
a label "LabelInA" in the same document. Then LyX would introduce the
reference as usual, i.e. \ref{LabelInA}. Now we want to insert a
reference to a label "LabelInB" in same document B. LyX would detect
that the label is in another document (easy, since we have to choose
that document in the cross-references dialog) and introduce the
reference as, e.g., \ref{DocumentB:LabelInB}.
Now, when we include document A in a third document and compile, LyX
would rename all labels of document A (and of all documents, including
the master) by adding a prefix "DocumentA:" and would update the
references (in the same document A) to those lables accordingly (in
our example would change \ref{LabelInA} to \ref{DocumentA:LabelInA}).
Note that the \ref{DocumentB:LabelInB} would not be modified, and that
would not be necessary, since the labels in document B would also be
renamed by adding prefix "DocumentB:" to them.
I actually thing that, with independence of doing what I say or not,
differentiating whether a reference points to a label in the same
document or in another document is wise to facilitate debugging, in
case this is necessary.

Hi!
I have just realized that when importing child documents, the labels
of the different documents may overlap. That is, the same label may
have been used, e.g., in two child documents. Does LyX take this into
account and add any kind of prefix to the labels of the children
documents? If not, I think this would be a nice feature, rather than
having to modify manually the overlapping labels.
No, you don't really want LyX to do that. It should be possible to
reference labels in one child from the other children---which it is, as
things are. If you start modifying the labels themselves, then you would
have also to modify the references to those labels. But then how do you
know which one you meant to reference?
