Cant get exporter to set `$id` instead of `id` for schema id.

[jpwijbenga]

I'm trying to export a given schema to generate draft 7, which means use '$id' instead of 'id'. Trying with context passed to exporter, but it will keep generating id not $id.

Bug or am I doing it wrong?

So the picture I posted is the fix because it doesn't work without third ande fourth line.

Also, I looked through readme and tests, but couldn't find anything about setting version wrt. export.

Any info?

I also just try to manually set to $ownerSchema->{'$id'} and this is so weird.

php-json-schema/src/Structure/ClassStructureTrait.php

Line 106 in 2b99251

foreach ($properties->getDataKeyMap() as $propertyName => $dataName) {

I found that, even we've already set key data mapping :

$ownerSchema->addPropertyMapping(Schema::PROP_ID, 'id');

On json serialize wil use id rather than setted data mapping, because the previous key data mapped has been ignored or not substitute with current data key set.
