JSF 2.0 provides support for ordering the configuration resources. We can use partial ordering (represented by the <ordering> tag) and absolute ordering (represented by the <absolute-ordering> tag).
Partial ordering is specific to a single configuration document. We can use the <before> and <after> tags to indicate that a certain document should be processed before or after another document. Nested inside the <before> and <after> tags, we may have the <others/> tag, which indicates that a certain document should be processed before (respectively after) all the other documents that are sorted.
Listed here is an example where we have documents A, B, C, and faces-config.xml alias D:
