I am kind of sure I exploited the claimed behaviour of Saxon in the past 
to extract data from documents that were not well-formed; however, I 
can't get your example to work either so my claim was wrong or at least 
too general.

In the W3C test suite for XSLT 3 
(https://dvcs.w3.org/hg/xslt30-test/file/tip/tests/strm/si-iterate, if 
you can get through to it which has been a challenge at least for me 
today) there is at least one test case (si-iterate-094.xsl) where 
xsl:iteral/xsl:break is used and where Saxon (tested here with 9.8 EE) 
outputs a message saying "early exit" (if run with "-t" option) to 
indicate it abandoned parsing before reading through to the end of the file.
