Content referenced by example HTML files

When SVG content is brought into HTML via the <object> or <embed> tags the unpainted background of the SVG content is rendered as opaque white.

When SVG content in brought into HTML via the <img> tag the unpainted background of the SVG content is rendered as transparent.

It seems that the <img> tag behaviour is far more useful for compositing content and the correct model for SVG content.

Using the <img> tag is undesirable as it seems to treat the SVG content as an image and then text selection and links in text do not work. These do work when the content is brought in with <object> or <embed> but then the opaque white background limits the usefulness of SVG content.
