Subject: [xsl] XPath 3.0 question: What are function annotations? From: Dimitre Novatchev <dnovatchev@xxxxxxxxx> Date: Sat, 1 Mar 2014 15:26:21 -0800 |
In the XPath 3.0 Proposed Recommendation, section, 3.1.5.3 "Function Coercion", http://www.w3.org/TR/xpath-30/#id-function-coercion describes the properties of the function returned by the coercion in the following bulleted list: * name: The name of F . * parameter names: The parameter names of F. * signature: Annotations is set to the annotations of F. TypedFunctionTest is set to the expected type. * implementation: In effect, a FunctionBody that calls F, passing it the parameters of this new function, in order. * nonlocal variable bindings: An empty mapping. The third bullet above in particular says: "signature: Annotations is set to the annotations of F. TypedFunctionTest is set to the expected type" My question is: What are function annotations and why they are nowhere defined in the document? Note: The XQuery function that is used as example, does not contribute to making this section more understandable -- on the contrary. Why do the authors assume that anyone that uses XPath should know XQuery? -- Cheers, Dimitre Novatchev --------------------------------------- Truly great madness cannot be achieved without significant intelligence. --------------------------------------- To invent, you need a good imagination and a pile of junk ------------------------------------- Never fight an inanimate object ------------------------------------- To avoid situations in which you might make mistakes may be the biggest mistake of all ------------------------------------ Quality means doing it right when no one is looking. ------------------------------------- You've achieved success in your field when you don't know whether what you're doing is work or play ------------------------------------- To achieve the impossible dream, try going to sleep. ------------------------------------- Facts do not cease to exist because they are ignored. ------------------------------------- Typing monkeys will write all Shakespeare's works in 200yrs.Will they write all patents, too? :) ------------------------------------- I finally figured out the only reason to be alive is to enjoy it.
