filter

Hi All

I had a filter question need help, many thanks in
advance !!

Instead of being filtered by [starts-with(@ref,'GRP')]
Is there a way  use the fact that it is a
/xs:element/xs:complexType/xs:sequence/xs:element[(_at_)maxOccurs=
some value] (to identify/filter the 'GRP' element)

There are several places in the XSL(the XSL is for the
schema in the back) using this filter :

<xsl:key name="byGRP"
match="xs:element[not(starts-with(@ref, 'GRP'))]"

use="generate-id(preceding::xs:element[starts-with(@ref,
'GRP')][1])"/>
        
<xsl:key name="elements" match="xs:element" 
        use="generate-id((preceding-sibling::xs:element |
self::xs:element) [starts-with(@ref,
'GRP')][last()])"/>

<xsl:template match="xs:sequence">
...
        <xsl:for-each select="//xs:element[starts-with(@ref,
'GRP')]">
        ...
        <xsl:for-each select ="(xs:element |
xs:choice/xs:element | xs:sequence/xs:element |
xs:choice/xs:sequence/xs:element)[starts-with(@ref,
'GRP')][1]">
        ...
</xsl>
