RFR: 8330542: Template for Creating Strict JAXP Configuration File [v15]

[Joe Wang]

> Add two sample configuration files:
> 
>   jaxp-strict.properties: used to set strict configuration, stricter than jaxp.properties in previous versions such as JDK 22
> 
>>   jaxp-compat.properties: used to regain compatibility from any more restricted configuration than previous versions such as JDK 22
> 
> Updated on 5/16/2024
> 
> Design change:
> The design is changed to include in the JDK two configuration files that are the default jaxp.properties and jaxp-strict.properties, instead of three, dropping jaxp-compat.properties.
> 
> Updated on 5/18/2024
> 
> Withdraw changes to jaxp.properties. The original idea was to match jaxp-strict.properties with regard to the properties. However, that change impact the configuration process, resulting in tests that verify the process to fail.
> 
> Updated on 5/23/2024
> 
> Provide a template `jaxp-strict.template` instead of a properties file. This template can be used to create custom configuration files.
