This causes the following whitespace (particularly the NL) not to be
output. A trick I once learned from Jeni Tennison.

Yes. It isn't there and this is the sole reason I included the text of
this stylesheet module in my answer.

In XSLT 1.0 when using a boolean value in an arithmetic (numeric)
expression -- that is as an argument of an operator or function that
requires a numeric argument, the boolean value is converted to a
number using the following rule:

number(true()) = 1

number(false()) = 0
