RE: [xsl] Can we have a <xsl:attribute> inside a <xsl:variable>?

Wrong question. xsl:attribute writes an attribute to the result tree, which
isn't what you want to do.

In XSLT 1.0 you want:

<xsl:variable name="prefix">
   <xsl:choose>
      <xsl:when test="$var1">
         <xsl:value-of select="$var1"/>
      etc.

In 2.0 you can write

<xsl:variable name="prefix" select="if ($var1) then $var1 else $var2"/>
