Notes refsect1, langref=>language

First up, we need a notes refsect1. I redid the empty() manual page today, and decided that we definitely need a "Notes" section for things that just don't fit anywhere else. http://livedocs.homelinux.com/en/function.empty.html Is there any opposition to creating this? I'm not sure where I'd incorporate the notes on pages like stream_select (vast number of warnings/notes/cautions) either. Secondly, Are there any problems with changing the <part id="langref"> to <part id="language"> in manual.xml.in? It makes sense, as all the children sections are prefixed with "language." and not "langref.". If this is done, a patch for errors.php should be included too. Best wishes, Aidan
