The use of the MIME multipart message format would also help to speed up the display of figures by sending image data at the same time as the HTML+ document. Another possibility would be to allow image data to be embedded in the document using an EMBED element in place of the SRC attribute. Binary data could be represented using the MIME character encoding or the more compact ASCII base 85 encoding, as used in Adobe's PDF. The drawback with this approach is the inability to use format negotiation. As a result, the EMBED element has been dropped from the current draft.
