First:

If you want to select a string literal you have to quote it:

<xsl:variable name="aVar" select="'when var'"/>


Second:

The variable is out of scope outside of xsl:choose.
You can avoid that this way:

<xsl:variable name="aVar">
   <xsl:choose>
        <xsl:when test="do a test">
		<xsl:value-of select="'when var'"/>
 	</xsl:when>
 	<xsl:otherwise>
 		<xsl:value-of select="'otherwise var'"/>
 	</xsl:otherwise>

   </xsl:choose>
</xsl:variable>
<xsl:value-of select="$aVar"/>
