I have the following pasted into a current page at the bottom and while it will save and render correctly, missing the formatting caused by CONF-4490, it will not allow me to preview the addition. I get a dialog saying SyntaEerror: illegal character.

<sdn:outputExit>
<sdn:output value="This application will now exit. Goodbye."/>
</sdn:outputExit>

If I delete all the content between the

lines then I get a dialog saying SyntaEerror: syntax error.

If I delete everything then I can preview the page. Regardless of what the dialog syas, I can always save the page and it will display correctly, it is only the preview which seems to be screwed up.
