| | WDVL: Elements and Attributes Are Case-Sensitive |
 | | Unlike HTML, which is case insensitive (as is the SGML metalanguage of which HTML is an appplication), XML is strictly case-sensitive, and so therefore is every application of XML (e.g., XSLT, MathML, SVG and so forth, plus any languages you create). |
