Summary: "Unknown encoding error" with "iso-8859-15"

Initial Comment:
hello,
I have 2 files which looks similar except for the encoding. One (OK) is "iso-8859-1", the other (KO) is "iso-8859-15".
I have tried EXPAT from version 2.0 to 2.1 and both generates an error when parsing the "iso-8859-15" file.
Can you please explain if this is a bug or not and if not why??
I have downloaded expat from this link
http://sourceforge.net/projects/expat/files/expat_win32/2.1.0/expat-win32bin-2.1.0.exe/download
and
http://sourceforge.net/projects/expat/files/expat_win32/2.0.0/expat_win32bin_2_0_0.exe/download

and this is my result
C:\Expat-2.1.0\Bin>dir
