The string-join() solution works well in XMLSpy and solves my problem.
The "separator" solution does not work in XMLSpy.

Assuming XMLSpy is implementing the spec correctly, $indent_4 is a sequence
of 4 strings, not a string of 7 characters as you suggest. It comes out as a
string of 7 characters when you output it using xsl:value-of, because
xsl:value-of by default inserts spaces as separators between the strings in
a sequence.
