Saxonica EE : compilation of xslt and transformation can we overwrite or ignore select value of

Question

we are using saxonica EE license , i want to know if we can ignore or overwrite (ignore is preferred) select value of (which calls some other apps logic, which we want to ignore), example code as below

<xsl:value-of select="cpi:setHeader($exchange, 'content-type', 'application/xml')"/>

here want to ignore this select, it doesnt have any significance in the over logic of transformation. is it possible to ignore a select in saxonica ?

Answer 1

You could write

<xsl:value-of 
   use-when="function-available('cpi:setHeader', 2)"
   select="cpi:setHeader($exchange, 'content-type', 'application/xml')"/>
