 == Deploying Environment Specific Context XML Files
 
-A xref:xml/index.adoc[Jetty context XML file] file can be applied to _all_ webapps deployed to a particular `environment` by adding a file named `{ee-all}.properties` containing the location of the file.
+xref:xml/index.adoc[Jetty context XML file] files can be applied to _all_ webapps deployed to a particular `environment`.
 
-This environment-specific Jetty context XML file will be applied to the webapps _before_ any context XML file associated with the webapp.
-Thus, it can be used to configure general defaults to all webapps for a given `environment`, allowing a webapp-specific context XML file to further refine or override that configuration.
+Add a properties file to the deployment directory that contains a property naming the location of the xml file to apply.
+The properties file name must be prefixed by the name of the `environment`.
+For example `ee8.properties, ee8-more.properties ee8-other.properties` would all apply to the `ee8` environment.
+
+The properties files contain at minimum one property whose name is prefixed with `org.eclipse.jetty.deploy.environmentXml`.
+So for example `org.eclipse.jetty.deploy.environmentXml, org.eclipse.jetty.deploy.environmentXml.more, org.eclipse.jetty.deploy.environmentXml.other` are all acceptable as names.
+Each property configures the location of a context xml file to apply to a context when it is being created and deployed.
+The location may be either absolute or relative to _the parent of the deployment directory_.
+So if your webapp deployment directory is `$JETTY_BASE/webapps`, then `$JETTY_BASE` will be used to resolve any relative filenames.
+
+All environment-specific Jetty context XML files will be applied to the webapp _before_ any context XML file associated with the webapp.
+The order in which they are applied is determined by _the name of the properties that define them_.
 
 IMPORTANT: The contents of the environment specific context XML file may only contain references to classes appropriate for that environment.
 
-The `{ee-all}.properties` file must be in the same directory as the webapp being deployed.
-It must contain the property `jetty.deploy.environmentXml` set to the location of the context XML file.
-The location may be either absolute or relative to the parent of the deployment directory (usually `$JETTY_BASE`).
+For example, given the previous example of a `$JETTY_BASE/webapps/wiki.xml` and its accompanying `$JETTY_BASE/webapps/wiki.properties` file that declares the `wiki` webapp should be deployed to environment `{ee-current}`, files called `$JETTY_BASE/webapps/{ee-current}.properties` and `$JETTY_BASE/webapps/{ee-current}-feature.properties` can be defined to further configure the webapp.
 
-For example, given the previous example of a `$JETTY_BASE/webapps/wiki.xml` and its accompanying `$JETTY_BASE/webapps/wiki.properties` file that declares the `wiki` webapp should be deployed to environment `{ee-current}`, a file called `$JETTY_BASE/webapps/{ee-current}.properties` can be defined containing the following:
