Error162"&navid" is an invalid character reference in the value for the "href" attribute. This may be because the '&' character was not escaped as "&amp;". This is a common error that should be fixed (even though it still works most of the time). Ampersands should be escaped with "&amp;" even when specifying script variables. Web browsers will convert "&amp;" back to '&'. Example: href="script.php?var1=value1&var2=value2" should be href="script.php?var1=value1&amp;var2=value2" (note that '&' in this example was escaped with "&amp;").

Warning3The natural primary language is not specified. It is highly recommended that the "lang" and/or "xml:lang" (for XHTML) attributes be used with the "html" element to specify the primary language. For example, add the attribute lang="en" for English or lang="fr" for French. Specifying the language assists braille translation software, speech synthesizers, translation software, and has other benefits.
