It is presented as an example, but I agree with your comment. The error 
message is better without that part.

The message appears as a separate paragraph, giving it more weight. 
Moreover, in practice, the type attribute is not needed for <script> and 
<style> element (it has been made even formally optional in HTML5, and 
although this does affect validation of XHTML 1.0 documents, it's not 
useful to emphasize these attributes).

In reality, text/javascript works more reliably than any alternative. 
But the type attribute is really best omitted in practice, even though 
some formal rules require it. (It never causes any good, and it is known 
to cause harm when misspelled, which occurs fairly often.)
