| Note | The source attribute points to an external source. When used on an element describing a schema component (<classRef>, <dataRef>, <elementRef>, <macroRef>, <moduleRef>, or <schemaSpec>), it identifies the source from which declarations for the components should be obtained. On other elements it provides a pointer to the bibliographical source from which a quotation or citation is drawn. In either case, the location may be provided using any form of URI, for example an absolute URI, a relative URI, a private scheme URI of the form tei:x.y.z, where x.y.z indicates the version number, e.g. tei:4.3.2 for TEI P5 release 4.3.2 or (as a special case) tei:current for whatever is the latest release, or a private scheme URI that is expanded to an absolute URI as documented in a <prefixDef>. When used on elements describing schema components, source should have only one value; when used on other elements multiple values are permitted. |
