If then else sequencing

[gregsdennis]

These tests are for validators that use parsers that maintain serialization order of JSON. Only these validators can be expected to fail these tests.

Any validator that does not maintain order should pass anyway.

[gregsdennis]

For this case, a validator processing the keywords in serialization sequence would process as follows.

then - no annotations from if -> skip
else - no annotations from if -> skip
if - produces no failure condition, just annotation for then and else to read -> valid

But this case is invalid, so the test should fail for such a validator.

[gregsdennis]

Similarly here.
