the Microsoft XSD inference tool is a good, free solution. Many XML editing tools, such as XmlSpy (mentioned by @Garth Gilmour) or OxygenXML Editor also have that feature. They’re rather expensive, though. BizTalk Server also has an XSD inferring tool as well. edit: I just discovered the .net XmlSchemaInference class, so if you’re using .net … Read more
It turns out, the answer is that what I’m seeing is a Byte Order Mark, which is a character that tells whatever is loading the document what it is encoded in. In my case, it’s encoded in utf-8, so the corresponding BOM was EF BB BF, as shown below. To remove it, I opened it … Read more
There is no need to use the classpath: protocol in your schemaLocation URL if the namespace is configured correctly and the XSD file is on your classpath. Spring doc “Registering the handler and the schema” shows how it should be done. In your case, the problem was probably that the spring-context jar on your classpath … Read more

No, an XML namespace takes the lexical form of a URI but does not have to be retrievable according to W3C Recommendation: Namespaces in XML 1.0 (Third Edition): The attribute’s normalized … Read more
They’re for allowing multiple markup languages to be combined, without having to worry about conflicts of element and attribute names. For example, look at any bit of XSLT code, and then think what would happen if you didn’t use namespaces and were trying to write an XSLT where the output has to contain “template”, “for-each”, … Read more

Here’s the relevent section of the spec: Element Declaration Schema Component Property {target namespace} Representation If form is present and its ·actual value· is qualified, or if … Read more
Namespace related attributes in XML and XML Schema (XSD) xmlns is part of the W3C Namespaces in XML Recommendation: The prefix xmlns is used only to declare namespace bindings and is by definition bound to the namespace name http://www.w3.org/2000/xmlns/. In your example, it declares that http://maven.apache.org/POM/4.0.0 is the default namespace for the elements in your … Read more
There is a difference, yes. XML that adheres to the XML standard is considered well formed, while xml that adheres to a DTD is considered valid.
The default values for minOccurs and maxOccurs are 1. Thus: <xsd:element minOccurs=”1″ name=”asdf”/> cardinality is [1-1] Note: if you specify only minOccurs attribute, it can’t be greater than 1, because the default value for maxOccurs is 1. <xsd:element minOccurs=”5″ maxOccurs=”2″ name=”asdf”/> invalid <xsd:element maxOccurs=”2″ name=”asdf”/> cardinality is [1-2] Note: if you specify only maxOccurs attribute, … Read more
