Can't you just work with the one variable $somelanguage (capital l?)
throughout? If you define somelanguage at the top of the stylesheet:

	<xsl:stylesheet ... >
	   <xsl:param name="somelanguage" select="'en'"/>

	   <xsl:template match="/">
	     Foo: <xsl:value-of select="$somelanguage"/>
	   </xsl:template>
	</xsl:stylesheet>

NOTE: double quotes around "'en'", otherwise it will take the value of the
ELEMENT en, which doesn't exist. Then specifying it on the command line to
e.g. saxon should cause it to be overridden e.g:

	> saxon test.xsl test.xsl
	Foo: en

	> saxon test.xsl test.xsl somelanguage=Spanish
	Foo: Spanish
