What does XHTML do and why is it important?

Answer:
XHTML is designed to do everything HTML can, only better. It complies with XML parsing systems, rather than systems based off of the Standard Generalized Markup Language (SGML); this allows computers to read webpage documents (or anything written in XHTML) more accurately and with more speed.
