RelaxNGn

RelaxNGn is a schema language for XML, designed to be more user-friendly and flexible than its predecessor, RelaxNG. It was developed to address some of the limitations and complexities found in RelaxNG, particularly in terms of readability and ease of use. RelaxNGn aims to provide a more intuitive and concise way to define the structure and constraints of XML documents.

One of the key features of RelaxNGn is its compact syntax, which allows for more concise and readable schema definitions. This is achieved through the use of a more streamlined grammar that reduces the verbosity often associated with XML schema languages. RelaxNGn also supports a wider range of data types and constraints, making it more versatile for various XML applications.

The language is designed to be easily extensible, allowing users to define custom data types and constraints as needed. This flexibility makes RelaxNGn suitable for a broad spectrum of XML use cases, from simple document structures to complex data models.

RelaxNGn is part of the RELAX NG family of schema languages, which includes RelaxNG and TREX. Each of these languages has its own strengths and is suited to different types of XML validation needs. RelaxNGn, with its focus on simplicity and readability, is particularly well-suited for users who need to define and validate XML schemas with minimal effort.

In summary, RelaxNGn is a schema language for XML that offers a more user-friendly and flexible alternative to RelaxNG. Its compact syntax, support for a wide range of data types, and extensibility make it a valuable tool for XML developers and users.
