Subject: [PATCH] The `columns` attribute of the `index` type was
 `xs:NMTOKENS`, therefore not allowing a comma, which is needed when multiple
 columns need to be specified. (I've checked the XmlDriver code for this) It
 should be the same as the `columns` attribute of the `unique-constraints`
 type, namely `xs:string`.
