RE: [Springframework-developer] Anybody know historical purpose of dependency-check 'default' value?

[Alef A. <al...@jt...>]

I don't know,

I've searched a bit through my email archives and have attached a couple
of mail related to the introduction of the dependency checking features.

I think we (or however implemented this) chose to have a default
attributes to allow for future modification of the default if needed??
