Ryan - thanks for the help. I had read the manual from cover to cover,
but I had read an older version which didn't contain this information. I
really appreciate the references.

The Tigris archive search feature doesn't work very well. Everyone

I wasn't aware of the best practices document. Took me a minute to
find it. You appear to be talking about this document:
It doesn't appear to have been modified significantly since it was
added to the repository in April 2004, and the section you're talking
about has not been modified at all since then. The document still
talks about limitations of Subversion 1.0. Doesn't sound very up-to-
date to me.
I recommend you read the book instead. The Branching and Merging
chapter has a section on Common Use Cases which describes two
different types of branching: release branches and feature branches.
You're talking about the former, while the best practices document
only seems to address the latter. Here's the section in the book:
