Syntactic details
XML tags are case-sensitive. (<H1> is not the same as <h1>.
White space in the data between tags is relevant. But within the markup itself and within quoted attribute values, white space is normalized (removed).
XML allows you to specify different character set encodings. <?xml version=‘1.0’ encoding=‘UTF-8’ ?>
Predefined entities:
- < replaced by <
- & &
- > >
- ' ‘
- " “
