using TYPE abap_trans_parmbind_tab in xslt

hello.

i try to use

TYPE abap_trans_parmbind_tab contained in type-pool ABAP

inside xslt transformation.

the value is transported into xslt using PARAMETERS in CALL TRANSFORMATION.

my question is how to  declare sap:type  inside xslt

for this parameter ( param_tab ),

so i can use it's values in the transformation.

<xsl:param name="PARAM_TAB" sap:type="?"/>

thanks

Ronen
