See what happens here if the SRC attribute is used with <HR>
which should override the default look of the horizontal rule by substituting the graphic
image pointed to. The look, if it worked, might be similar to this:
See here whether your user agent supports the HTML 3.0 attribute:
The CLEAR attribute would allow the <HR> line
to meet the side of an image, or else to go below it, depending upon the value
set for this attribute. This first one uses <HR CLEAR="LEFT">.
It should extend from the left margin to some point on the picture at the right.
This next one uses <HR CLEAR="ALL">, so it should go
under the picture, if your user agent understands this attribute.
If not, then this should reconstruct what it would look like if it were
implmented to show <HR CLEAR="ALL"> correctly:
CLEAR="LEFT" means move down until the left margin is
clear, CLEAR="RIGHT" is the same for right margins,
CLEAR="ALL" is for both margins, and also such values as
CLEAR="40en" and CLEAR="100px" have been
suggested in the description for HTML 3.0 draft.
The other attribute, MD might take such a value as
md5:jV2OfH+nnXHU8bnkPAad/mSQlTDZ which would be some binary encoded or encrypted
string associated with some particular generation of the SRC resourse, so as to
be able to detect if it has been modified and if so not to use it. This attribute is simply
provided as a part of HTML 3.0 wherever the SRC attribute is used. Like
LANG, it has no relavance to <HR>.
