Mark, I was thinking more about Parallel deployment section of Tomcat Docs
https://tomcat.apache.org/tomcat-9.0-doc/config/context.html
Just a simple mention like
"
If you want to get the current webapp version number in a servlet you should
use org.apache.catalina.webappVersion attribute, like this:
String webappVersion =
(String)request.gteServletContext().getAttribute("org.apache.catalina.webappVersion");
"

The list is in the Javadoc:
https://tomcat.apache.org/tomcat-11.0-doc/api/org/apache/catalina/Globals.html
Where else would you like to see it? The where may change which steps
are required to update the docs.
