As Nartin i think will point out later in this thread :) in XSLT 3 you
can use shadow attributes and _mode="$staticmode" where $staticmode is
a stylesheet parameter declared with static="yes" - for any XSLT
attribute. I've also used this for xsl:output's doctype attribute,
which is neither an AVT nor an expression.
