解説 |
A child constraint is required when the mode attribute has the value replace or add (or is not specified, as add is the default). No child elements are permitted when the mode attribute has the value delete. At least one child element is required when the mode attribute has the value change. |
||||||||||||||||||
例 |
This constraint uses Schematron to enforce the presence of the spanTo attribute (which comes from an attribute class) on the addSpan element: |

例 |
<constraintSpec ident="demo-c2"
scheme="schematron"> <desc>Implement an accessibility rule which says that pictures should have textual explanations</desc> <constraint> <sch:report test="not(tei:figDesc or tei:head)"> You should provide information in a figure from which we can construct an alt attribute in HTML </sch:report> </constraint> </constraintSpec> |
||||||||||||||||||
例 |
This constraint uses SPITBOL (a language which is not expressed in XML) to check whether the title and author are identical: |
