Bug in PydanticBaseModel for ISO20 Messages

[TGruett]

Hi,

i figured out two problems with the pydantic model for ISO 20 while testing the schedule mode.

• the parking fee has the wrong alias
• the AbsolutePriceSchedule misses the id attribute [see 8.3.5.3.49]

While the fix of the first problem is straight forward, the id attribute in the AbsolutePriceSchedule is a bit more complex. I'm not sure how to properly model elements of type xs:ID, especially its uniqueness. Perhaps someone else knows how to deal with this?

Thank You.

Thank you for reporting this @TGruett :). I have opened a PR for this and will include this in the next release.
Kind regards,
Shalin.
