svg_loader: Fix invaild '<' nested check

When Type is DOCTYPE, Child Entities start with '<'.
This condition is valid when general Elements (svg, g, path etc) are used.
Add a Doctype check to if condition.
(There can be various cases related to '<' nested case.
But for now, I only add Doctype considering the side effect.)
