Currently, the Label code only supports text attributes, but we should support other types, such as image or SVG labels. From https://bugzilla.mozilla.org/show_bug.cgi?id=291501#c8: > Maybe the correct thing would be to do this in XBL (when our XBL patch > is in) and then insert different anonymous content based on the mime type of > the external document.
This is what currently happens. We start loading an external resource for xf:label if it has @src on it. When the stream starts coming back, we check to see what the content type is. If it is not "text/plain", we throw an error and quit out. This bug is to add support for more types (like images or SVG).
Is text/html or application/xhtml+xml also planned?
