When using the All constraint on an objects embedded as a property, each object is also validated.

For example, take the following configuration:

<property name="favoriteColours">
    <constraint name="All">
        <option name="constraints">
            <constraint name="NotBlank"/>
            <constraint name="Type">
                <option name="type">\Colour</option>
            </constraint>
        </option>
    </constraint>
</property>

In this case, I'm finding that validation configuration for \Colour are also being triggered, where I would expect it to only be validated if I were also using the Valid constraint.
