- missing sources for some hyphenation patterns files (e.g. hyph-en-gb in the hyph-utf8 packages explicitly states that it's generated from an unpublished word list)
Essentially all the hyphenation patterns were originally generated from wordlists that are not available. Including US English. Although I know it is suboptimal, it seems to me that the hyphenation patterns are themselves source. They can be understood and modified, on their own. Many of the hyphenation pattern files were in fact modified by hand from patgen's output. I believe there is an analogy with fonts. Many forever-regarded-as-free fonts have an "upstream" version; all of Adobe's and Bitstream's fonts, say, were certainly created with proprietary tools (Fontographer, Ikarus, whatever). But I think it is not wrong to consider the "derived" Type1's (or OTF's or whatever) as free, given their release under a free license. The fonts can be used, modified, etc., on their own, even though in a theoretical sense they are not the ultimate upstream source. Ditto hyphenation patterns. - MeX license which can be interpreted to disallow selling or modification - ec contains code from MeX-licensed pl fonts, has a license considered I will talk to the Poles about the MeX license. I doubt they will have a problem with switching to Knuth's current text or the LPPL or whatever. k
