Version Control With Subversion Source

In trunk/doc/book:

* TODO: Note that we should standardize "use-case" vs. "use case".
* book/ch05.xml: Don't misinform about what UUID means.
* book/ch06.xml: Be consistent about the example server name.
* book/ch09.xml (svn import refentry): Rename "vendors" to "misc", to avoid a
generic import example implying things about vendor branching.
