Note that the result of xsl:message differs from implementation to implementation. For example,
MSXML silently discards your xsl:message that has no terminate="yes", so this solution would work
only if you use it like: 
<xsl:message terminate="yes"><xsl:copy-of select="$var"/></xsl:message>
This thing is stated at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/xmrefxslmessageelement.asp
:
<<Attributes
terminate 
Specifies whether the transformation should terminate upon executing this instruction. This
attribute can have one of two string values: "yes" or "no". When the terminate attribute is set to
"yes", the content of the element is displayed as the part of the system-level error message, and
the transformation terminates. When it is set to "no", the transformation proceeds, ignoring the
error message. The default value is "no". >>

Another solution: dump your variable in the output file (if you output XML, not text):
<variable-dump name="$var1"><xsl:copy-of select="$var1"/></variable-dump>
...
<variable-dump name="$var2"><xsl:copy-of select="$var2"/></variable-dump>

so later you can look into the output file and look for variable-dump elements.
I recomend you to use this method conditionally: set a parameter of your XSLT file (i.e.: debug)
and use like this:
<xsl:if test="$debug">
  <variable-dump name="$var1"><xsl:copy-of select="$var1"/></variable-dump>
</xsl:if>
This way, you can switch easily between debug mode and production mode.
