#2 Error while processing XSLT stylesheets

[Jeroen Hellingman]

While processing a collection of stylesheets with XSLTDoc 1.2.2, I got the following issue:

Error on line 446 of stylesheet.xsl:
XTTE0590: A sequence of more than one item is not allowed as the value of parameter $doc
(<xd:doc/>, <xd:doc/>, ...)
at xsl:for-each (file:/D:/Users/Jeroen/Documents/eLibrary/Tools/tei2html/tools

processing /XSLTdocConfig
Transformation failed: Run-time errors were reported

Platform: Windows; XSLT 2.0 processor: Saxon9HE.

The stylesheets I am trying to process are in https://github.com/jhellingman/tei2html (as well as the xsltdoc.config)

I've not yet been able to locate what triggers this.
