bug#21882: 24.5; DocBook dbnotn.rnc notation.class is missing PDF

[Daniel Barrett]

The file /usr/share/emacs/24.5/etc/schema/dbnotn.rnc has a definition
"notation.class" that contains a list of file types, such as "JPEG"
and "PNG". Please add "PDF" to this list. I can confirm that O'Reilly
Media, who I believe created the DocBook DTD, uses "PDF" for this
purpose in the DocBook source code of its books. (I am an O'Reilly
author.) Without "PDF", emacs nxml-mode reports that documents are invalid
when they are not.

Here is a diff:

$ diff -c dbnotn.rnc.orig dbnotn.rnc
*** dbnotn.rnc.orig     2015-11-11 19:53:07.960289145 -0500
--- dbnotn.rnc  2015-11-11 19:53:24.816521679 -0500
***************
*** 65,70 ****
--- 65,71 ----
    | "JPEG"
    | "IGES"
    | "PCX"
+   | "PDF"
    | "PIC"
    | "PNG"
    | "PS"

Thank you very much.
