I think so ... TOMCAT_OPTS=" -Xmx128m -Xms64m "

So, I like to use both:
I defined a component
"<component ... "
with:
<parameter name="transformer-factory"
value="com.icl.saxon.TransformerFactoryImpl"/>
." that uses Saxon in cocoon.xconf
and i defined another transformer (xslt-saxon) that calls this component
with:
"<xslt-processor-role>org.apache.cocoon.components.xslt.XSLTProcessor/Saxon</xslt-processor-role>"
In WEB-INF/lib there is saxon652.jar
Here are the coplete extracts of my cocoon.xconf and sitemap.xmap:
# cocoon.xconf
<component
role="org.apache.cocoon.components.xslt.XSLTProcessor/Saxon"
class="org.apache.cocoon.components.xslt.XSLTProcessorImpl"
logger="core.xslt-processor">
<parameter name="use-store" value="true"/>
<parameter name="incremental-processing" value="false"/>
<parameter name="transformer-factory"
value="com.icl.saxon.TransformerFactoryImpl"/>
</component>
# sitemap.xmap
<map:transformer name="xslt-saxon" pool-grow="2" pool-max="32" pool-min="8"
src="org.apache.cocoon.transformation.TraxTransformer">
<use-request-parameters>false</use-request-parameters>
<use-browser-capabilities-db>false</use-browser-capabilities-db>
<xslt-processor-role>org.apache.cocoon.components.xslt.XSLTProcessor/Saxon</xslt-processor-role>
</map:transformer>
