function-available()

---

The function-available() function tests whether a given function is available in this particular XSLT processor. This allows you to design strategies for falling back gracefully if it is not.

Syntax:

boolean function-available(string) 

Arguments:

The name of the function being tested for. The name should be a QName. If the value is not a string, it will be converted to one using the rules of the string() function.

Result:

True if the function is available, false otherwise.

Defined: XSLT, section 15.

NS support: Supported.
