Bug 29556: MARC21slim2MODS.xsl broken by duplicate template name "part"

This patch removes a redundant section from MARC21slim2MODS.xsl which
was breaking the option to use unAPI in the OPAC using MODS format.

To test, apply the patch and view a record in the OPAC using unAPI,
e.g.:

/cgi-bin/koha/unapi?id=koha:biblionumber:1&format=MODS

You should see an XML file where previously there would have been an
error.

What about:

git grep 'xsl:template name="part"'                                                                                                                         [11:13:29]

This seems to be an authority record export format which can be tested by viewing an authority in the staff interface and choosing Save -> MADS. The export appears to work correctly.

> koha-tmpl/intranet-tmpl/prog/en/xslt/MARC21slim2MODS3-1.xsl

This seems to be a bibliographic record export format which can be tested by viewing a bibliographic record in the staff interface and choosing Save -> MODS. The export appears to work correctly.

These two files appear to be unused. I could only find references to them in .po files.

Pushed to master for 22.05, thanks to everybody involved!

Jonathan:

Here is what makes the difference (yes it is confusing at least):

MARC21slim2MODS.xsl contains
   <xsl:include href="MARC21slimUtils.xsl"/>
This is our include that contains the template named part.

But MARC21slim2MADS.xsl contains
    <xsl:include href="http://www.loc.gov/marcxml/xslt/MARC21slimUtils.xsl"/>
This is NOT our include, but the LOC one.
And it does not include a template named part.

Etc.

Thanks for checking. See former comment too.

What does not help either, is that opac/unapi runs INTRANET xslt sheets:

sub get_xslt_file {
    my ($format, $format_to_stylesheet_map, $format_info) = @_;
    $format = lc $format;

    my $marcflavour = uc(C4::Context->preference('marcflavour'));
    return unless $format_to_stylesheet_map->{$marcflavour}->{$format};

    my $xslt_file = C4::Context->config('intrahtdocs') .
                    "/prog/en/xslt/" .
                    $format_to_stylesheet_map->{$marcflavour}->{$format};
