xml-xmln [--dtd --relaxng --xsd] <xml_file>

--dtd
    Validate the XML document against its declared Document Type Definition (DTD).

--relaxng

--xsd
    Validate the XML document against a W3C XML Schema.

<xml_file>
    The path to the XML file to be checked or validated.

xml-xmln is a utility primarily used to check XML files for well-formedness and proper namespace declarations. It acts as a wrapper around the xml-check command, providing a simplified interface for XML validation. The command allows users to validate XML documents against various schema types, including Document Type Definitions (DTDs), RelaxNG schemas, and W3C XML Schemas. Its main purpose is to ensure that XML files adhere to XML syntax rules and, optionally, to specified schemas, which is crucial for data integrity and interoperability in XML-based applications. It's often found in Debian/Ubuntu systems as part of the xml-core package.

This command is primarily a wrapper; for more detailed control or different validation engines, xml-check or other dedicated XML processing tools might be necessary. It requires the relevant schema (DTD, RelaxNG, XSD) to be properly linked or accessible from within the XML document or externally specified by the underlying xml-check tool. It's a relatively simple and specialized utility, not a full-featured XML processing suite.

The xml-xmln command is typically found in the xml-core package on Debian-based Linux distributions. This package provides a system-wide framework for managing XML-related tools and configurations, including standardized wrapper scripts for various XML utilities.

It functions as a direct wrapper for the xml-check command. While xml-xmln provides a simplified interface for common validation tasks, xml-check offers more granular control over XML parsing and validation processes, and xml-xmln essentially passes its arguments to it.

xml-xmln is part of the xml-core package, which is a Debian-specific mechanism for managing XML tools and standardizing their behavior across the system. It was developed to provide a user-friendly wrapper for xml-check, simplifying the process of validating XML files against common schema types. Its development focus has been on providing a consistent and easy-to-use interface for basic XML validation within the Debian ecosystem, ensuring system-wide XML compliance and proper handling of XML documents.
