Validating Schemas and Message Instances
In Visual Studio, when you develop Schema artifacts, you have three options to test or validate this Schema through the UI. They are available through the context menu of a Schema in the Visual Studio Solution Explorer.
The Validate Schema option can be useful; for example, if you receive a Schema from a third-party or after you have completed work on a Schema that you built yourself. It will validate that the structure and implementation of the Schema is correct.
