Attributes Attributes
source specifies the source from which some aspect of this element is drawn.
Status Optional
Datatype 1–∞ occurrences of teidata.pointer separated by whitespace
Schematron
<sch:rule context="tei:*[@source]"> <sch:let name="srcs"  value="tokenize( normalize-space(@source),' ')"/> <sch:report test="( self::tei:classRef | self::tei:dataRef | self::tei:elementRef | self::tei:macroRef | self::tei:moduleRef | self::tei:schemaSpec ) and $srcs[2]"> When used on a schema description element (like <sch:value-of select="name(.)"/>), the @source attribute should have only 1 value. (This one has <sch:value-of select="count($srcs)"/>.) </sch:report> </sch:rule>
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.
