I don't know, given that you haven't provided it all. The key word here 
is "all" -- I don't see any generator declarations for example, and the 
$(WSDLS) variable is not defined. Please always provide complete example that 
I can unpack and try right away.

Did you check:

     http://boost.org/boost-build2/doc/html/bbv2/extending/features.html

among other things that page says for that dependency features you need to 
have explicit DEPENDS somewhere. If that still does not help, post a complete 
example and I'll look.
