aspect ratio:
xsl:choose
<xsl:when test="normalize-space(…formatAspectRatio) = ','"/>
<xsl:when test="…= '16:9,' or …= '16:9, '">
<f:string key="videoFrameSize">16:9</f:string>

clean up code:
Before:
<f:boolean key="kb:has_kaltura_id">
xsl:choose
<xsl:when test="$kalturaID != ''"><xsl:value-of select="true()"/></xsl:when>
xsl:otherwise<xsl:value-of select="false()"/></xsl:otherwise>
</xsl:choose>
</f:boolean>

After:
<f:boolean key="kb:has_kaltura_id"><xsl:value-of select="$kalturaID != ''"/></f:boolean>
