If it appears like that in your stylesheet, then it's not javascript code as
far as the XSLT processor is concerned, it's just a chunk of text to be
copied into the generated HTML document.

You haven't understood the processing model. The XSLT processor takes an XML
document and a stylesheet as input and runs a transformation whose output is
an HTML page. When the user selects something on a form, they are
interacting with the HTML page. The transformation by then has long ago
