Our opinion is that the following 3 struct tests are faulty as detailed

== struct-svg-201-t ==
>From line 54:
	var fs = svg.getFloatTrait("snapshotTime");
	if(fs == "3")
This amounts to a float value compared against a string, which
is a type mismatch.
Moreover, constructing floats from strings cannot be guaranteed produce
same result across implementations. The returned float valued could 
theoretically be in this case 2.99999 or 3.000001 depending on
Suggested fix: Get trait as string or require that 2.999 < fs < 3.001.

== struct-svg-203-t ==
The test uses SVG 1.1 Basic features and the reference image shows the
for an implementation that supports SVG 1.1 Basic. The test does not in
any way
indicate that both results are acceptable. What is the purpose of this
test from 
the SVGt 1.2 conformance point of view? 
Suggested fix: remove this test entirely.

== struct-discard-202-t ==
>From line 25:
      <rect x="100" y="50" width="100" height="100" fill="red">
		<discard xml:id="discard1"
And line 44
	<discard xlink:href="#discard1" begin="1s"/>

circleanim.repeat(1) should happen at 5s, so the latter discard gets
executed at 1s 
and discards the discard animation at line 26. The reference image
suggests that 
the expected result is that the discard at line 26 gets activated and
the top-left
circle is exposed. 
Suggested fix: Either update the reference image to show red rectangle
in top-left
corner or remove the last discard animation.
