In addition to YAML, in what other format can provider services be described?

In addition to YAML, provider services can be described in the following formats:

• JSON — a widely used format, similar in structure to YAML but more strict and less human-readable.
• XML — an older but still used format for describing configurations and services, especially in corporate systems.
• HCL (HashiCorp Configuration Language) — used in infrastructure as code tools, such as Terraform.
• TOML — a simple configuration file format, sometimes used for describing services.

The choice of format depends on the system requirements, parsing convenience, and team preferences.
