You mean you didn't spend Christmas day memorising the Xpath/xslt/xquery
drafts, shame on you!

for is part of Xpath2 (and also Xquery, but it is being used in Xpath
here) return is just part of the for syntax it's always 
for $variable in "something" return "something"
which is like an xpath version of
<xsl:for-each select="something">
<xsl:variable name="variable" select="."/>

separator attribute is from the xslt2 version of xsl:value-of and
xsl:copy-of. If these things return a sequence then the separator gets
put inbetween each one.
