How to say it in XSD? (xs:list, xs:enumeration, ...)

Max
Suppose I have a simple type which is enumeration

<xs:simpleTyp e name="fontStyle ">
<xs:restricti on base="xs:string ">
<xs:enumerati on value="bold" />
<xs:enumerati on value="italic" />
<xs:enumerati on value="underlin ed" />
<xs:enumerati on value="strikeou t" />
</xs:restriction>
</xs:simpleType>

I want a type which is any combination of the above, so I write
<xs:simpleTyp e name="fontStyle Lst">
<xs:list itemType="fontS tyle"/>
</xs:simpleType>

But, this will also allow combinations like "bold italic bold". Which has no
sense.
I would like each possible value to be allowed only once in the list.
Is their a way to write down this restriction in XSD?

No, not for simple types like this. There is a way for complex types using
xsd:all, but that cannot be used for attribute values.

Hi All As per my understanding we use xs:key when we want to have a unique value for a element or attribute and keyref to refer to one of the unique values of that element or attribute. However I am not sure if this uniqueness is checked when we validate a document using XMLSpy Here is the protion of myschema

I'm trying to create a simple type that holds two different types. The first is IDREF and the second is an enumeration of string. When I generate a sample xml, I can enter any ID previously stated in the xml and validates correctly. When I try to use one of the enumeration in the drop down list, the xml will not validate. When I validate the xml in xmlspy, i get the error message "IDREF 'endofprogam': referenced ID 'endofprogam' was not found."...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
