CS3 Illustrator SVG layer output uniqueness - is there a switch?

Question

If I have two layers named the same, such as 'abc' when the SVG file is written it 'uniquifies' the instances, even though they are in separate graphs:
<g id="top" ..>
      <g id="block1" ..>
           <g id="abc_1"  ...>
      <g id="block2" ..>
           <g id="abc_2"  ...>
Is there a way to switch this off in CS3 so I get
<g id="top" ..>
      <g id="block1" ..>
           <g id="abc"  ...>
      <g id="block2" ..>
           <g id="abc"  ...>
if this is a software limitation, does CS5 solve this issue?
This is a problem when writing programatic graphics - every addressable layer has to be unique. What a pain!

Answer 1

I realize that <g> is not a class, and I'm not talking about inheritance.
Let me pose the problem in a different way, maybe that will help the understanding. The reason you don't understand the analogy is because you don't understand the problem.
Let's say I'm drawing a street. I draw the street as a set of lines that make a polygon, group them, and call it 'main street'. The polygon is put into a layer called "San Francisco".
I create another layer called "Chicago", which also needs a 'main street'. I copy the 'main street' from the 'San Francisco' layer into the 'Chicago' layer.
According to your claim, SVG written out as 'main_street_1' is correct because no 'main street' can be the same. So instead of saying Chicago's main street, I have to say 'main_street_1' and then figure out how illustrator assigned main_street_1.
So if I have 100 cities with 'main street', and I have 'main_street_56', I really have no idea which city it belongs to - when I know I want Cleveland's main street.
Then expand it to country. USA's Chicago's main street vs France's Nice main street. It just gets worse. I can't individually name each main street because illustrator needs all symbols unique.
If this isn't clear, maybe I can provide the actual example, but it's going to be technical.
