Validate numbers in frontend when there is a `totalDigits` constraint

For a XSD schema like this:


We will generate this (in Studio):


But it seems that is not being validated. A workaround would be setting `maximum` and `minimum` instead if the type of the number is `integer`, but it doesn't work decimal numbers. There is not JSONSchema equivalent of `xs:totalDigits` (since it accounts for digits on both sides of the decimal point). The backend C# classes are annotated with regex validation attributes, so it seems to work on the backend. So options:

* Manually validate `totalDigits` in frontend
* ???
