Define companies using a company element with an id:

<company id="comp1" name="Some Company">
  ..more details about the company
</company>

then refer to that company with a company ref element:

<company-ref ref-id="comp1"/>

then in your XSLT, have a template that matches "company-ref" that
gets the "company" element's @name:

<xsl:template match="description/company-ref">
  <xsl:apply-templates select="key('company-by-id', @ref-id)/@name"/>
..
