Overview

XmlAttribute represents an XML attribute with validation context

This class wraps XML attributes to provide a consistent interface for validation rules. It includes the attribute name, value, and namespace information needed for XSD validation.

Examples:

Create an XML attribute

attr = XmlAttribute.new("id", "12345", "http://example.com")

Access attribute properties

attr.name          # => "id"
attr.value         # => "12345"
attr.namespace_uri # => "http://example.com"
attr.qualified_name # => "{http://example.com}id"
