    14.5 Hiding style data from user agents

    Some style sheet languages support syntax intended to allow 
    authors to hide the content of STYLE elements from 
    non-conforming user agents.

    This example illustrates for CSS how to comment out the 
    content of STYLE elements to ensure that older, non-conforming 
    user agents will not render them as text.

    <STYLE type="text/css">
    <!--
       H1 { color: red }
       P  { color: blue}
       -->
    </STYLE>

Most articles/reports I've seen on authoring CSS have indicated that it's
good practice to enclose the contents of <style> elements in comments.
If newer practices indicate that it would be better to *not* do this,
then I'll be glad to take a look at them and reconsider PmWiki's default.  :-)
