See bug #4802

When compiling the stylesheet included in that bug entry under the XX compiler, it fails:

Compiling stylesheet /Users/mike/bugs/2020/4802-Priest/webApp.xsl
Failed to compile stylesheet: Static error in XPath on line 70 in 4802-Priest/webApp.xsl {         array:for-each($cells, function ($c) {           f:swapRowCol($c, array {})         })}: 
Required type of second argument of f:swapRowCol() is array(map(*)): actual type is array(xs:error0)
Error Q{http://www.w3.org/2005/xqt-errors}XPTY0004 at xpath.xsl#963
    Failed to compile stylesheet

Also revealed in that bug report is that asynchronous execution complicates the diagnostics. When first run, the -master: document was not well-formed XML. The stylesheet compilation and loading of the master document happen in parallel, which means that the messages from both errors get output, which is rather confusing. I'm not sure there's much we can do about that.
