Ah, not that knowledge - I meant this:

<fo:block margin-top="30pt" margin-bottom="17pt" margin-left="51pt" 
margin-right="9pt" border-top-width="0pt" border-bottom-width="0pt" 
border-left-width="4pt" border-right-width="2pt" border-top-style="solid" 
border-bottom-style="solid" border-left-style="solid" 
border-right-style="solid" border-top-color="black" 
border-bottom-color="black" border-left-color="black" 
border-right-color="gray" font-family="Optima" font-size="12pt" 
font-style="normal" font-weight="normal"><fo:inline 
font-weight="bold">Diagram 5.4: </fo:inline>Version of inductive coupling 
using 0.5pF polyester capacitors.</fo:block>

How does this tell anyone that this once upon a time had a semantically loaded 
structural meaning such as 

<caption><strong>Diagram 5.4: </strong>Version of inductive coupling using 
0.5pF polyester capacitors.</caption>

 - this info is lost, but replaced by other pertinent presentation-related 
info. Not pertinent to anyone dredging up 'web' matter from the future 
though. If they needed to know that sort of thing, it's in the source doc. 
That's what I meant by 'null knowledge' - all that border stuff is not going 
to help you greatly if you're searching for captions.

Not convinced. In fact, using your examples, you're in danger of presenting 
possibly out of date possibly distributed possibly restored from backup etc. 
versions rather than to regenerate the freshest one and only. [strokes chin, 
makes tea, wondering if I'm actually right - nah - nobody ever does that with 
PostScript unless they're mad or talk to themselves.].
