[ACCEPTED]-Where to add a version to an XSD schema?-version
You can use the namespace of your xsd document
<xs:schema targetNamespace="http://yourcompany/yourapp/1.0" ... >
...
</xs:schema>
As 10 an example look at the xsd's defined by 9 w3.org, this is how they do it. Do note 8 that changing the version number here would usually 7 by definition be a breaking change for any 6 consumers of your xsd (no matter how small 5 the actual change was, or which part of 4 the version number you changed).
For less 3 impacting versioning, there seems to be 2 an agreement about putting a version attribute 1 at your root element:
<xs:schema version="1.0.0" ...>
...
</xs:schema>
According to the schema
element itself has a version
attribute:
<schema
attributeFormDefault = (qualified | unqualified) : unqualified
blockDefault = (#all | List of (extension | restriction | substitution)) : ''
elementFormDefault = (qualified | unqualified) : unqualified
finalDefault = (#all | List of (extension | restriction | list | union)) : ''
id = ID
targetNamespace = anyURI
version = token
xml:lang = language
{any attributes with non-schema namespace . . .}>
Content: ((include | import | redefine | annotation)*, (((simpleType | complexType | group | attributeGroup) | element | attribute | notation), annotation*)*)
</schema>
See 6 http://www.w3.org/TR/xmlschema-1/#key-schema, "3.15.2 XML Representations of Schemas"
However, if 5 you published the schema, then I think the 4 best way to deal with it would be to use 3 the target namespace. This would enforce 2 the right version being used (but break 1 compatibility)
