While we did provide programmatic APIs for adding servlets, filters and listeners, we have not exposed a full API for processing every element in the descriptor via APIs. Note that the programmatic APIs are not a complete replacement for the descriptor. It still makes sense to specify certain aspects via descriptors - just like in the case of annotations.

Ideally, every element (with some exceptions) would be settable in 3 ways, namely via:

• The traditional descriptor
• An annotation
• A high level programmatic API

Note that JSF 2.2 introduced a method that's between the descriptor and the programmatic API: a call-back in which the descriptor is exposed as a DOM tree and can be programmatically manipulated. See http://arjan-tijms.omnifaces.org/p/jsf-22.html#533 You could call this a low level programmatic API.

It might make sense to adopt the JSF 2.2 method for web.xml.
