Clauses 5.5.6 (
roleattribute), 5.5.14 (roleattribute), 5.5.16 (severityattribute)If the value of a [
flag,role,severity] attribute given in a schema is a variable reference, its value shall be dynamically evaluated. This mechanism is provided to enable the [...] value to vary, for example according to the selected phase and its in-scope variables.
Example 15. Dynamic evaluation of attributes
The following schema
<sch:schema defaultPhase='phase'> <sch:ns prefix='a' uri='b'/> <sch:let name='c' value='d'/> <sch:phase id='phase'> <sch:let name='flag' value='"foo"'/> <sch:let name='role' value='"bar"'/> <sch:let name='severity' value='"blort"'/> <sch:active pattern='foo'/> </sch:phase> <sch:pattern id='foo'> <sch:rule context='*'> <sch:assert test='false()' flag='$flag' role='$role' severity='$severity'></sch:assert> </sch:rule> </sch:pattern> </sch:schema>
would result in SVRL containing this failed-assert:
<svrl:failed-assert test='false()' flag='foo' role='bar' severity='blort'/>
