OK. Thanks for the reference. A little further down that thread, I finally
got the explanation of why LGPL is no good for ASF code!

http://archives.apache.org/eyebrowse/ReadMsg?listId=135&msgNo=1429

Reading Ken's message in light of this, it's a lot clearer. I'd focused on
this

>if a licence permits *linking* against
>a library, there's no prohibition on our packages requiring
>the library in order to run properly.

But it's clear that the 'viral' nature of LGPL section 6 (i.e.)

... provided that the terms permit modification of the work for the
customer's own use and reverse engineering for debugging such modifications

would attach restrictions on people who use ASF code that the ASF license
does not. e.g. They do not have to allow reverse engineering. So NO LGPL
imports.

OTOH, if someone had an LGPL implementation of a 'standard' interface, e.g.
the java crypto api, or an xml parser, that should be OK, since there
wouldn't be any LGPL code in the ASF code.

Is MPL or MPL-derived code OK? This is actually on point, as there may be a
replacement for the nsuml library available from the NetBeans project, which
uses the Sun Public License, which is a search-and-replace version of the
Mozilla Public License.

NSUML is being abandoned, and I've seen traffic on the argouml list
regarding replacing it with the metadata repository (MDR) library from
NetBeans.

Moreover, I'm actually interested in this because I use statecharts to model
servlet activity, and have done a few handwritten code generators for them.
I hadn't noticed before this that graph had anything to do with it.
