Upon further poking on the LoC website, I think I have answered my own
question.

This mrc2xml.pl program apparently converts marc records to an xml
format that
"... differs from the MARCXML schema by specifying each MARC data
element as an XML element." 
http://www.loc.gov/marc/marcxml.html
So yes, it converts to XML, but it doesn't convert to the current
MARCXML standard. 

This seems to be of limited utility, since it appears that most of LC's
and other folks' development work (stylesheets, etc.) is based on the
MARCXML schema. Opinions?

Our sysadmin just got mrc2xml.pl installed for me and I'm trying to
work
with it. Have a coupla questions, if anyone can help.

First, I thought, upon reading the documentation, that it would
product
xml output of bib records according to the current Library of Congress
standard. But I don't think it does; when I match up the basic data
element names from the mrc2xml.pl output with an LoC stylesheet, such
as
the MARC21toMODS stylesheet, nothing matches. The root element is
different, the way fields are handled and indicators are identified,
etc., don't match at all. Is there some other description file I
should
be using with mrc2xml.pl to produce standard output? Or perhaps I
should
say LoC standard output.

Second (may be moot now because of 1, but I'll need it eventually) I
thought I could just pop a reference to the
http://www.loc.gov/standards/mods/v3/MARC21slim2MODS3.xsl 
stylesheet into the xml and have the xml source file display in MODS.
But when I tried to add a reference to it, thus:
<?xml-stylesheet type="text/xsl"
href="http://www.loc.gov/standards/mods/v3/MARC21slim2MODS3.xsl";?>
I get:
Access is denied. Error processing resource
'http://www.loc.gov/standards/mods/v3/MARC21slim2MODS3.xsl'.
