Apple's official utilities had been dropped the word "Computer". We should follow them.

imac:~$ cat test.py
__import__('plistlib').writePlist({}, 'test.plist')
imac:~$ python test.py
imac:~$ cat test.py
__import__('plistlib').writePlist({}, 'test.plist')
imac:~$ python test.py
imac:~$ cat test.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
</dict>
</plist>
imac:~$ plutil -convert xml1 test.plist
imac:~$ cat test.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

imac:~$

I did a quick search and couldn't find any reference about this change, the examples in the apple doc still use 'Apple Computer'.
Do you have any reference that says that the correct doctype (now) uses only 'Apple'?

How about this example from Mac OS X Reference Library "Property List Programming Guide":

http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/PropertyLists/QuickStartPlist/QuickStartPlist.html

Perhaps the fact that Apple officially changed the name from "Apple Computer" to "Apple" back in 2007 also helps:

http://www.macworld.com/article/54770/2007/01/applename.html

This one had a short URL, you can search Google for "apple computer changes name" for more (Forbes, Information Week, etc.)

Do you have a reference where Apple docs written after 2007 use "Apple Computer"?

Also, on a Mac computer:

- start Xcode 3.2.1 and select Help->Developer Documentation
- type in the search box in the top right corner "property list"
- the second hit is "Property List Programming Guide"; click on it
- the second page gives the same example as the URL I put in msg98905
- it uses DOCTYPE with /Apple/ only

plutil is a command shipped with every Mac. See the example in my original post.

I agree that the DTD should be changed.

Fixed in r80279 (trunk) and r80280 (3.2). 

I won't backport to 2.6 and 3.1 because this is a mostly cosmetic issue and I do not want to risk breaking existing scripts.

r80279 and r80280 caused many buildbot to fail:

 i386 Ubuntu 3.x
 AMD64 Ubuntu trunk 
 AMD64 Ubuntu wide trunk 
 x86 Ubuntu trunk
 x86 XP-4 trunk 
 x86 XP-5 trunk
