# *sp:attr-if*
# Adds an attribute if a condition holds
# Example:
# <div sp:attr-if="@my_condition,class,coolDiv"></div>
# The attribute's value can be a scene variable, but not an expression: so
# <div sp:attr-if"@my_condition,attr_name,@attr_value" /> is valid, but
# <div sp:attr-if"@my_condition,attr_name,@attr_value_start+@attr_value_end" /> is not
