Customizations to JAXB bindings made by means of an external file containing binding declarations take the general form shown below.
<jxb:bindings schemaLocation = "xs:anyURI"> <jxb:bindings node = "xs:string">* <binding declaration> <jxb:bindings> </jxb:bindings>
schemaLocation is a URI reference to the remote schema.
node is an XPath 1.0 expression that identifies the schema node within schemaLocation to which the given binding declaration is associated.
For example, the first schemaLocation/node declaration in a JAXB binding declarations file specifies the schema name and the root schema node:
<jxb:bindings schemaLocation="po.xsd" node="/xs:schema">
A subsequent schemaLocation/node declaration, say for a simpleType element named ZipCodeType in the above schema, would take the form:
