How to reference global types in XSD?

Question

How to implement XSD inner reference to simpleType?

I am facing the error you see in the image below.

How to reference global types or elements in XSD

With `@targetNamespace`

^{[This half of the answer addresses the original question.]}

First define a namespace prefix on xs:schema for the namespace specified by @targetNamespace:

<xs:schema targetNamespace="http://example.com/know-type"
           xmlns:kt="http://example.com/know-type"
           ...
           />

Then use it where you reference global types in this namespace.

Use it to reference Money, which is causing your immediate error:

<xs:element name="TotalSum" type="kt:Money" />

Use it also where you reference PNGPictureType:

<xs:element name="Front" type="kt:PNGPictureType" />
<xs:element name="Back" type="kt:PNGPictureType" />

After making these changes, your XSD will be free of errors.

Without `@targetNamespace`

To reference Money, replace type="xs:Money" with type="Money", and be sure that the target of the reference is globally, not locally, defined (your is):

<xs:element name="TotalSum" type="Money" />

No change is needed in this case for the references to PNGPictureType because it already properly addresses the no-namespace global types without using an improper namespace prefix.

Hi! I dont have any real namespace like you mentioned xmlns:kt="http://example.com/know-type". I guessed is possible to define simpleType "locally" within a file. That what I need... Is it possible to do? – NoWar Feb 23 '17 at 16:50

@Dimi Please show (as text, not in an image) a complete input XML document that should be a valid instance of your schema. Thanks! More help: http://stackoverflow.com/help/mcve. – Mathias Müller Feb 23 '17 at 16:56

@Dimi If your instance documents are in no namespace at all, then you need to remove the `targetNamespace` attribute from your XML Schema. Having this attribute means that instance documents look similar to: ``. – Mathias Müller Feb 23 '17 at 17:02
Yes. You are right. Also in this case I have took out the `xs:` and keep the type name only. It is like . Please correct your answer as well. And thank you so much! – NoWar Feb 23 '17 at 17:09

@Dimi: The XSD that you posted has a `xs:schema/@targetNamespace`, which means that any XML meant to be validated against it will have to be in the namespace given by the value of `xs:schema/@targetNamespace`. It also means that references to elements and types within the XSD have to take into account the namespace. The changes I've shown in this answer demonstrate how to do this; no corrections are necessary unless you've changed your XSD to remove the `targetNamespace`. – kjhughes Feb 23 '17 at 17:12
@Dimi: I've added a *without* `targetNamespace` explanation to the answer to cover both ways for you. – kjhughes Feb 23 '17 at 17:23
Hi! Would you mind to help with another XSD issue please? http://stackoverflow.com/questions/42440634/xml-signature-element-is-not-declared – NoWar Feb 24 '17 at 14:05
@Dimi: Answered that one for you too. – kjhughes Feb 24 '17 at 14:21
