Appendix 3 – Doctypes
A 3.1
Introduction
Doctype abbreviates 'Document type Declaration' which tells a browser which 'Document
type definition' (DTD) to use to interpret a page. The Doctype also includes the URL of a
file containing the DTD details.
The Doctype must appear on the first line of code for a page.
Note Actually on an XHTML page an XML declaration may precede this but this can result
in problems with some browsers. KompoZer does not insert this declaration. Files without
an XML declaration use UTF-8 character coding.

Note For HTML Doctypes when Nvu inserts a document type declaration, it omits the
URL This has the undesirable effect of triggering some versions of MSIE into the so called
'quirks mode'.
