I assume you mean the <script> element, there is no <javascript>
element. And, no the validator *should not* ignore the content of the
script element, if it's within the HTML/XHTML document, it *must* be
processed according to the rules of SGML for HTML, or XML for XHTML.
In HTML, the script element is declared to contain CDATA, which is
parsed as ordinary character data up until the first occurance of ETAGO
(End-Tag Open) "</". When the ETAGO is encountered, it must be the
end-tag for the the script element, which may be either </script> or the
widely unsupported, yet valid, SHORTTAG NET (Null End-Tag) </> for the
script element. The validator does not understand JavaScript and does
not treat the content of the script element as JavaScript.
That is why the validator issues errors for script like this:
document.write(" ... </a>")
However, document.write() should generally be avoided in favour of the
more well structured and standardised DOM interface functions that don't
work with raw strings of markup like that.
See this FAQ entry:

That is, of course, the recommended option for all scripts.
