Image element should embed a tag attribute containing the caption of the image

The Python method
element.Image(url="http://.../smiley.png", caption=":)")
generates the following HTML code:

-------------
<img
  contenteditable="false"
  alt=":)"
  src="http://.../smiley.png">
-------------

ideally it would generate

-------------
<img
  contenteditable="false"
  alt=":)"
  title=":)"  <------
  src="http://.../smiley.png">
-------------

The reason for this is that it occasionally is beneficial to add extra text
information to an image, information which should be tightly coupled to the
image and only displayed upon request (ie when hovering with the mouse over
the image).

An text to image replacemente robot might unintentionally replace a
character sequence with an image. Having the title tag would let the
recipient of the message still decode the original text message with this
additional piece of information.
