prefixlocalName

PrefixLocalName is a term used in the context of XML namespaces to refer to the combination of a namespace prefix and a local name. In XML, namespaces are used to avoid naming conflicts by qualifying names with a URI. A PrefixLocalName is a string that consists of a namespace prefix followed by a colon and then the local name. For example, in the XML element "xsd:schema", "xsd" is the namespace prefix and "schema" is the local name, making "xsd:schema" the PrefixLocalName.

The namespace prefix is an alias for the namespace URI and is defined within the XML document using the xmlns attribute. The local name is the actual name of the element or attribute within the context of that namespace. The combination of the prefix and local name is used to uniquely identify elements and attributes within the XML document.

PrefixLocalNames are particularly useful in XML schemas and other XML-based technologies where multiple namespaces are used. They help in distinguishing between elements and attributes that might otherwise have the same name but belong to different namespaces. For instance, in an XML document that uses both the XSD and XSI namespaces, elements like "xsd:schema" and "xsi:schema" can coexist without conflict because they have different PrefixLocalNames.

In summary, PrefixLocalName is a fundamental concept in XML namespaces, providing a way to uniquely identify elements and attributes within an XML document by combining a namespace prefix with a local name. This helps in managing and processing XML documents that utilize multiple namespaces.
