reuse of tag to keep stable URLs?

[Brian H. Toby]

I am trying to get beyond my rather simple use of svn and would like  
some advice. My goal is to have two releases of a package available,  
one bleeding edge and the other stable. I want to keep the URLs to  
both releases stable. This seems like a reasonably common thing that  
one would want, but google has failed to find this discussed (probably  
because I am using the wrong lingo to describe what I want.) Anyway, I  
can see two ways to implement this:

1) Keep the bleeding-edge release in the trunk and use a tagged  
version for the stable release. When I am ready to make a new stable  
release, I delete the stable tagged release from the repository and  
then copy the trunk reusing the same tag name.

2) keep the stable release as the trunk and work on the bleeding-edge  
release as a branch. When I am ready to make a new stable release, I  
use merge --reintegrate and commit to update the stable release and  
then delete and recreate the  bleeding-edge branch.

Option 2 seems to be the way that svn is designed to be used, but is  
more complex. I guess it is more robust, if someone commits a change  
to the stable. Are there any other reasons to go that route? Is there  
an even better choice?
