Strictly speaking this gives you a variable whose value is an empty
string - not quite the same thing as 'no value'.

There is no assignment statement in XSLT.  What you are doing is
creating a *new* variable whose name is $monday (rather than simply
monday).  $monday is not a legal variable name, so your processor
should be signalling an error.

It depends what you are trying to do.  It may be as simple as putting
<xsl:variable name = "monday" select = "'Monday'"/>

(in which case the top level declaration is probably unnecessary).

If not, you will need to tell us what your stylesheet is trying to
achieve.
