Missing definitions in examples

[jacyimp]

Hey!

Any reason why there are missing definitions in examples?

For instance, example#0 has name, animal, breed, stats, traits; All are missing from php definitions except for name and age.

Is this intended? I can try fixing them if it's not intended. Thought it'd be better to ask first.

For my own implementation, I struggled a bit with how to implement <trait order="2">Friendly</trait>

such as:

<?xml version="1.0"?>
<pet>
    <name>Bear</name>
    <animal>Dog</animal>
    <breed>Australian Labradoodle</breed>
    <stats age="4.0" />
    <traits>
        <trait order="2">Friendly</trait>
        <trait order="2">Bonkers</trait>
    </traits>
</pet>

edit: by using two properties #[Str('/trait/@order')] for "2", and #[Str('/trait')] for "Friendly"

We could add such a case to one of the examples too.

I found out that there's a possibility for nullability to with required later when diving into the code. This could also be an included in the examples.

Let me know how to proceed. And thanks!
