Hi,

Considering a DTD "sampledocument.dtd" and two documents, one starting with:

<!DOCTYPE sampledocument SYSTEM "sampledocument.dtd">
...

the other one starting with:

<!DOCTYPE sampledocument SYSTEM "sampledocument.DTD">
...

The two xml documents only differ by the case of the file name of the refered local DTD. On a Windows host both xml documents are regarded as valid (XMLSpy), on a UNIX host the second document is not, because the validator cannot find the DTD (UNIX file system is case-sensitive).

XML as such is case-sensitive, but are the values of system identifiers case-sensitive as well?

I did not find any explicit hint on that, can anybody point me to where this matter might be specified?

Thanks a lot

Thomas.
