  • XML is case sensitive, so it also follows the XML Schema is also case sensitive.


    The reason is performance. The CPU only sees bits not letters. The character A is encoded differently than the a, so any case insensitive compare must convert all alphabet characters to the same case. Using ASCII there is not much overhead (single clock cycle per character) but with Unicode it gets a lot more complicated.


    By being case sensitive, XML eliminates the need to translate all element and attribute names to a single case.
