peculiar approach chart

I stumbled on this chart while preparing for an upcoming flight to Knoxville:

http://www.naco.faa.gov/d-tpp/0604/00218HIL5L.PDF

I see some unfamiliar graphics on this chart, namely the dotted lines in both
the profile and plan views, and the candy-striping at the top and bottom of the
page. I perused the legend at

http://www.naco.faa.gov/d-tpp/frntmatter.pdf

but don't see any description or explanation of these graphic elements.

The procedure is named "HI-ILS...". What is that? High altitude? High speed? I
notice that there are published transitions starting at 13000 feet, and also
that there are minima listed for approach category E, whereas most approaches
seem to show only categories ABCD.

A PDF search of the AIM at http://www.faa.gov/ATPubs/AIM/AIM.pdf for the string
"HI-ILS" produced no hits.

A google search of rec.aviation.ifr produced some hits, including the
information that a HI-ILS approach is a military procedure, and noting that
"...the approaches in question are not published in the civil US Terminal
Procedures Publications". I guess that's now changed.

So if these approaches are now published in the civil publications, shouldn't
the graphics be described in the corresponding legend publication? Anyway, what
is the significance of the candy stripes and the dotted lines?

For reference, there is also a corresponding ILS approach to the same runway:

Might I ever fly a HI-ILS approach in my Mooney?
