It's in the works. There have been a couple of last minute changes to the
XSLT spec but it should be formalized as a W3C Recommendation by next week.
At that time I will make whatever final adjustments are necessary before
putting the stylesheet out on the EAD Help Pages.

> 1.  The MARC catalog record for the collection is downloaded from the OPAC

> standard feature of such software.  The record is in the MARC transmission
> format.   The collection's id number is assigned as the file name, e.g.
> P1905 or 1186.

> 2.  The staff member goes to that directory at the DOS command line (both
> conversion applications are run from a commnd line) and types "convert
> filename", thereby executing a DOS batch file called convert.bat.
>
> 3.   That batch file executes two operations.
>
> The program marcxml.exe from Logos Research converts the record from the
> MARC transmission format to the MARC DTD format as an XML document.
>
> James Clark's XT processor software then uses an XSL stylesheet to
> transform
> the document from the MARC DTD structure to EAD.
>
> The resulting file is output as a fle named Collection_Number.xml, e.g.
> p1905.xml or 1186.xml.
>
>
> 4.  The resulting xml file is loaded into an XML editor for enhancement,
> adding various values required for the <eadheader> section.

> The principal ambiguity of this method is that one cannot always predict
> what went into a MARC 500 field and therefore reliably map its contents to
> the correct EAD element.  Any adjustments are made manually in the xml
> editing software.  There may be other areas in your MARC implementation
> where there are similar ambiguities.
>
> As others have reported, success may be had with other tools including the
> perl scripts available from the LIbrary of Congress to do the step of
> converting the data from the MARC transmission format to XML in the MARC
> DTD

> 1XX,
> 6XX, and 7XX
> would have to be mapped to a single subfield $a within the appropriate
> fields with the subfield codes and indicator values being edited
