In fact, the FO30 spec says that if an env variables does not exist, it should return the empty sequence. I propose to fix this test by testing for emptiness instead. 123850 1 mike 2015-10-22 14:21:42 +0000 Agreed. I have rewritten the test to read: <xsl:value-of select=" every $s in ('user', 'USER', 'shell', 'SHELL', 'path', 'PATH', 'zzz', '', '%$£*!') satisfies if (available-environment-variables() = $s) then exists(environment-variable($s)) else empty(environment-variable($s))"/> 123851 2 mike 2015-10-22 14:31:35 +0000 I have similarly rewritten function-1601 123856 3 abel.braaksma 2015-10-22 15:57:18 +0000 Thanks. I also rewrote it, I will check if I inadvertently overwrote your changes...
