TextEdit code design decision [message #1773658]

I analyzed thoroughly the TextEdit class and its documentation provides as follows:

Quote:

An edit tree is well formed in the following sense:

a parent edit covers all its children

children don't overlap

an edit with length 0 can't have any children

I couldn't find the design reason for not allowing overlapping children. The code only throws a MalformedTreeException if a child is tried to be inserted and overlaps with their potential siblings.

Any help of why it was decided like this is very much appreciated.
