Xtscript functions can also be called from html
HTML only
The Xtscript function being called must first be defined in a Xtscript on the same page
There are two formats for this function
<xt:call function="name" first_var="value" more_vars="value" last_var="value"/>
Or like this
<xt:call function="name" args="$first_var=value;$another_var=value;$last_var=value" />
