Another criteria that should be taken in to account is : does the action
have pipeline-building children or not ?
The "theme-selection" action above can be either pre/intra/post-matching
depending on the precedence order of URL patterns. An intra-matching
example :
<!-- non-themed high precedence URL patterns -->
<map:match>...</map:match>
<!-- themed URL patterns -->
<map:act type="theme-selection">
<map:match>...</map:match>
<map:match>...</map:match>
</map:act>
<!-- non-themed low precedence URL patterns -->
<map:match>...</map:match>
With this new criteria :
+1 for pre/intra/post-matching non-empty actions
+1 for pre-matching empty actions : this can be used to setup some
application-level context
-0 for intra/post-matching empty actions : I don't see any real
usefullness for them.
