Grundschicht of 2 IV H.7b triggers bug in newer Saxon versions

[thvitt]

After updating xmlcalabash1-gradle to 1.5.2, the text-unemend step of generate-emendations.xpl fails with an IndexOutOfBounds exception from Saxon while transforming prepared/textTranscript/2_IV_H.7b.xml. The problem remains after updating calabash and saxon to the newest versions via the dependency mechanism.

It works fine with XML Calabash Version 1.1.21 (for Saxon 9.8.0.8/HE). It is still broken when manually depending on the newest XML Calabash, classpath group: 'com.xmlcalabash', name: 'xmlcalabash', version: '1.3.2-100', which loads Saxon 10.5 HE.

Stack Trace:

• Problem occurs when running the text-unemend.xsl step with 2 IV H.7b (document/archival/bb_cologny/G-30_07.xml). All previous documents worked fine.
• Problem does not occur when running Saxon-HE 10.5 from the command line, with a physical file as input
