That's ISO not I-S-O
What's in a name? And no, its not an acronym... Anyway, the article is a blog post about one Ken Holman who is stepping down from the ISO subcommittee responsible for SGML. The first part of the post is about the ISO name bit but the second part has to do with how some of the ISO committees operate and some possible changes in the wind especially in regards to our good friends at SC34 (you know, the document format handlers).
Apparently there is talk of setting up another working group to deal specifically with office document formats... it seems "the volume of work required of ODF and OOXML is threatening to overwhelm the members of those [existing] groups".
