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.

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. + +> So, somehow, we have to know the meaning of a field before we can use it properly, which kind of goes against the idea of having something generic. + +> --[[KathrynAndersen]] + ----- I was just looking at HTML5 and wondered if the field plugin should generate the new Microdata tags (as well as the internal structures)? -- [[Will]]
