Re:  passing a sequence as a parameter
simplest change to what you posted is probably something like this:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    <xsl:param name="my_param" as="xs:string?" />
    <xsl:param name="my_params" as="xs:string*" select="tokenize($my_param,',')"/>
    <xsl:output indent="yes"/>
    <xsl:template match="/root">
    <xsl:template match="user">
           <xsl:for-each select="name"> 
	     <xsl:variable name="p" select="position()"/>
               <xsl:if test="$my_params[$p] = 'true'">
                       <xsl:value-of select="."/>

$ saxon9 rg.xml rg.xsl my_param='true,false,true'
<?xml version="1.0" encoding="UTF-8"?>

If you are calling teh stylesheet via an APi that allows seqeunce values
to be constructed and passed in externally you may set your my_params
parameter directly to that sequence, and ignore the my_param parameter,
but conversely if as I demonstrate above you are using a simple APi like
the saxon command line that doesn't allow structured values to be passed
in you can ignore the my_params parameter and set the my_param parameter
to a single string with comma separated values, the sequence will tehn
be constructed as the default value of $my_params.
