We'll read up on this stuff. Thank you. but I have more comments in line.

Defaults for Symbols are easy. Just contribute your defaults to

thank you, I will read up.
Configurations are different, and have caused quite a few people
problems. There's been talk of adding an override method
MappedConfiguration to allow this, see Howard's comment:
https://issues.apache.org/jira/browse/TAP5-45
You can easily code around this anyhow, it's just a matter of having an
extra service to hold the default configuration.
1) will read up.
2) We also have usecases for overriding mapped ordered configuration. (
Like setting up our own RenderSupport!!) So if someone adds overrides,
please add them to all forms of contributions!
3) You can't easily do this for MetaData, since the MetaDataLocator
throws an exception for non-existent meta lookups. I guess I can wrap
that in a helper method that will do what I want.. look for "meta", and
use it, if exception, try "meta-default", etc. But that's just not
cool, and what if I have 2 or three layers of users, and each wants to
set/override the meta..
thank you for giving me something to read! :)

Alright, so maybe my response below is a little rant/flame. But
really, are you truly saying that Tapestry doesn't allow libraries to
properly set defaults, then allow users of the library to override
those defaults??
<rant>
This is a library! A library needs to be able to set defaults, that
users of the library can override for their particular purposes.
Else, every setting becomes required for every user to set!
How does tapestry deal with Symbols? Do we have to always set
tapestry.production-mode, or page pooling configuration? Or with the
"default" mime-type of a page? Would you want to force everyone to
set the mime-type of every page to be "text/html"???
Tapestry MUST support a way to set defaults reliably for Symbols and
configurations reliably, and yet allow users of those to override
them! I really can't see any other way. Are you truly saying that
this basic use case can't be supported?
