It does not permit multiple instances, unless you are able to specify
shutdown port as well.
Though I suspect that for running as a service that value can be "-1", thought
1) I have not tested whether that is true lately.
2) if Tomcat is installed to be integrated with an IDE, e.g. to be
used with Eclipse IDE, an explicit shutdown port will be needed. That
is because when you create a "Server" in Eclipse, it copies
configuration files from existing installation of Tomcat and later
uses the port specified there to stopping launched Tomcat.

And perhaps using some well known scheme, eg:
connector.<protocol>.<param>
port="${connector.http.port}" address="${connector.http.address}"
etc ..

Or define portBase (or httpPort, httpsPort, shutdownPort, ajpPort) in
catalina.properties - easier for users to edit.

I don't know whether that is a good fit for this discussion, but I think
technically the nicest way is to choose a port range and a port
convention, for example:
- AJP: NN09
- HTTP: NN80
- Shutdown: NN05
- HTTPS: NN43
and let the user choose NN or NNN. In server.xml it could be
port="${portBase}80" etc. and in the startup options -DportBase=NN.

One more idea:
maybe generate server_1.xml etc. at build time from conf/server.xml
E.g. with
http://ant.apache.org/manual/Tasks/replaceregexp.html

Sorry, I did not notice that shutdown port has already been changed.
(I looked in the file, but did not notice that my "svn update" command
had failed).

Defining the port numbers as properties in catalina.properties does
work. I did it once.
But, because of the above quoted use case, I think that server.xml
created by the installer should stay as close as possible to the one
packed in a zip archive.
That means to use 8005 by default and to be able to change it.
One more feature to be added: to be able to do not install HTTP or AJP
connector if it is not needed.
Technically, I think the installer can print the whole <Connector>
element by itself instead of printing just the port. (If user choses
not to install the connector, the same text can be printed as an XML
comment).
By the way, I searched whether there exists some subroutine to perform
string replacements, so that we do not need to maintain several
fragments of the file.
Here are some pointers:
