Hi, Gary,
Yes, paths can be "interesting"! They are aggressively evaluated
and don't have quite as much freedom in compsition as one might
expect.

To fix the immediate path-syntax problem, Try this instead
print structure-block/1/:count

You're getting (the value of structure-block/1) followed by "/" and
the value of count, where it appears that you wanted the value of
(structure-block/1/ followed by the value of count).
However, my curiousity is killing me... You wrote

I can't figure out how your block relates to XML. It isn't the output
from parse-xml, it doesn't correspond to XML by replacing the block
brackets with tag brackets, and it isn't literal REBOL either...
>> structure-block: [ [ 1999.01.0161 book=O poem=1 line=1 Greek]
[ [ 1999.01.0162 book=O poem=1 line=1 English ] ]
** Syntax Error: Invalid tuple -- 1999.01.0161.
** Where: (line 1) structure-block: [ [ 1999.01.0161 book=O poem=1
line=1 Greek]
If you can provide a few more clues, I might be able to give you some
more useful suggestions than just the minor syntax check above.
