Having just run the xml tests, the first time for quite a while, note there has been a change in the output for test xml/case-1510101.[xml/conf]...
Looking back, this test was added due to https://sourceforge.net/p/tidy/bugs/777/, which fixed a bug, and it seems this bug remains fixed, the purpose of the test...
It seems the only change in the pretty print output are just indent changes... this change could have been around for quite a time... did not exactly check the commit that causes it...
It is certainly unrelated to the current xml PR #595...
Thus, baring any objections, propose to update the xml-expects\case-1510101.html to current output...
Comments welcome... thanks...
