Templates are supposed to be meaningful even when unrendered. This means
that a template cannot break the rules of HTML, which state that <style> and
<script> tags can *only* contain text content.

There are various workarounds, like the tal:content="string:...." trick
described in other postings on this list. For example:

<style type="text/css" tal:content="string:
p {
    color: ${request/bodycolor};
}
">
p {
    color: red;
}
</style>

The above is legal HTML, will render correctly in a browser even when the
template isn't expanded, and interpolates the 'bodycolor' variable from the
request into your stylesheet.
