Assuming the primary input is

<root>
	<record>
		<c2>AD</c2>
		<c3>AS</c3>
		<cn>002</cn>
		<short.name>
			<lg.vers lg="ss">text</lg.vers>
			<lg.vers lg="tt">text</lg.vers>
                         <lg.vers lg="ts">text</lg.vers>
                 </short.name>
         </record>
</root>

and the second XML document is

<root>
	<record>
		<short.name>test</short.name>
		<long.name>text</long.name>
		<iso.code2>AD</iso.code2>
		<source.lang>bg</source.lang>
	</record>
	<record>
		<short.name>test</short.name>
		<long.name>text</long.name>
		<iso.code2>AD</iso.code2>
		<source.lang>tt</source.lang>
	</record>
	<record>
		<short.name>test</short.name>
		<long.name>text</long.name>
		<iso.code2>DZ</iso.code2>
		<source.lang>bg</source.lang>
	</record>
</root>

then this stylesheet copies everything from the primary input document 
and in the short.name element of each record elements adds new lg.vers 
elements:

<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   version="1.0">

   <xsl:strip-space elements="*"/>
   <xsl:output indent="yes"/>

   <xsl:param name="sd" select="'test2009091002.xml'"/>
   <xsl:variable name="srs" select="document($sd)/root/record"/>

   <xsl:template match="@* | node()">
     <xsl:copy>
       <xsl:apply-templates select="@* | node()"/>
     </xsl:copy>
   </xsl:template>

   <xsl:template match="short.name">
     <xsl:copy>
       <xsl:apply-templates select="@* | node()"/>
       <xsl:apply-templates select="$srs[iso.code2 = current()/../c2 and 
not(source.lang = current()/lg.vers/@lg)]" mode="new"/>
     </xsl:copy>
   </xsl:template>

   <xsl:template match="record" mode="new">
     <lg.vers lg="{source.lang}"><xsl:value-of 
select="short.name"/></lg.vers>
   </xsl:template>

</xsl:stylesheet>

creates the output

<root>
    <record>
       <c2>AD</c2>
       <c3>AS</c3>
       <cn>002</cn>
       <short.name>
          <lg.vers lg="ss">text</lg.vers>
          <lg.vers lg="tt">text</lg.vers>
          <lg.vers lg="ts">text</lg.vers>
          <lg.vers lg="bg">test</lg.vers>
       </short.name>
    </record>
</root>
