I have 2 questions about encoding:

1) Are there some kind of list with all the encoding possibilities, lile
iso-8859-1 etc ?

2) If I use this syntax: <?xml version="1.0" encoding="iso-8859-1" ?> my
page loads ok. If I just capitalize the phrase like: <?xml Version="1.0"
Encoding="iso-8859-1" ?> the page do not loads anymore. I know that XML is
case sensitive, but with the declarations too? Are there any way to change
this behaviour?
