You are right in that we may have cross-references between children documents. I still think that my proposal of automatically renaming
labels is a good idea. What you say is actually not a problem is a little of care is taken by LyX when inserting cros-references.
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?
