[xsl] Providing a value for the 'select' attribute

["Mark" <mark@xxxxxxxxxxxx>]

Hi,
I have been using the following idiom when providing a value for bselectb in 
statements like <xsl:param>, <xsl:variable>, etc., when the value provided 
is not an xsl object. Is this correct or is some other form preferred?

<xsl:param name="file-type">
   <xsl:text>.htm</xsl:text>
</xsl:param>

Thanks,
Mark
