Dear all,

I have recently been working with MARCXML to MADS stylesheet
(http://www.loc.gov/standards/marcxml/xslt/MARC21slim2MADS.xsl) as this
stylesheet has become an integral part of the latest versions of
Evergreen ILS and is now used during authority records processing.

I have encountered an error while trying to transform MARCXML genre/form
authority records from the National Library of the Czech Republic. An
example of such a record is attached. (The 755 field uses zero as the
first indicator which is not compliant with MARC specs but even if the
indicator is changed to nothing/space, the error remains the same. A
non-XML MARC21 version of the record is available from
https://aleph.nkp.cz/F/?func=direct&doc_number=000131796&local_base=AUT.)

To process the file I have used xsltproc
(http://xmlsoft.org/XSLT/xsltproc.html).

When trying to process the file (xsltproc MARC21slim2MADS.xsl
americke_romany.xml > output.xml), the following error message pops up:

"xsl:attribute: Cannot add attributes to an element if children have
been already added to the element."

Josh Stompro from the Evergreen ILS community has come up with a simple
solution to the issue:

"If I swap lines 1084 and 1085 then the error goes away and both the
genre(155) and related genre(755) show up in the transformed xml."

For more details and suggestions please see Evergreen ILS main mailing
list archives:

Do you think this might be a bug in the stylesheet which could be fixed
in the official release of the stylesheet
(http://www.loc.gov/standards/marcxml/xslt/MARC21slim2MADS.xsl)?

Thank you in advance for considering the issue!
