Find attribute of node derived from extended base of ComplexType

Hi,

I want to know wheter or not an ancester of a node has an attribute maxOccurs 
and the value of this attribute.

For nodes like the countries in the example below this is no problem with:

<xsl:when test="ancestor::*/@maxOccurs">
        <xsl:value-of select="ancestor::*/@maxOccurs"/>
</xsl:when>


I get the '3' of the node <xs:element name="ACountry" minOccurs="0" 
maxOccurs="3">.


The question now is:
How do I find the attribute and get the 'unbounded' value of the element:
        <xs:element name="AnEntry" type="AnEntryType" maxOccurs="unbounded"/>

when the current node is i.e: 
<xs:element name="ANumber"> of the extended base of the complexType 
"AnEntryType"?

Any Ideas? Your help is greatly appreciated!

Thanks and best regards,

Peter
