namespace processing (the default handler would HTML-escape text fields
scrub, html fields, safeurl()ify url fields, etc.)
+> So, are you saying that getting a field value is sort of a two-stage process? Get the value from anywhere, and then call the "security processor" for that namespace to "secure" the value? I think "namespaces" are really orthogonal to this issue. What the issue seems to be is:
+
+ * what form do we expect the raw field to be in? (text, URL, HTML)
+ * what form do we expect the "secured" output to be in? (raw HTML, scrubbed HTML, escaped HTML, URL)
+
+> Only if we know both these things will we know what sort of security processing needs to be done.
+
+>> Fieldsets are orthogonal to the security issue in the sense that you can use
+>> them without worrying about the field security issue, but they happen to be
+>> a rather clean way of answering those two questions, by allowing you to
+>> attach preprocessing attributes to a field in a way that the user
+>> (supposedly) cannot mingle with.
+
+> There is also a difference between field values that are used inside pagetemplate, and field values which are used as part of a page's content (e.g. with ftemplate). If you have a TITLE, you want it to be HTML-escaped if you're using it inside pagetemplate, but you don't want it to be HTML-escaped if you're using it inside a page's content. On the other hand, if you have, say, FEEDLINKS used inside pagetemplate, you don't wish it to be HTML-escaped at all, or your page content will be completely stuffed.

+

I was just looking at HTML5 and wondered if the field plugin should generate the new Microdata tags (as well as the internal structures)? <http://slides.html5rocks.com/#slide19> -- [[Will]]
