AttributeName(pattern)
Returns true if the pattern (a regular expression or string literal) is found in the attribute AttributeName of the current note. This is used with String data type attributes, but can also be used with URL and File types.
List/Set type attributes can also be tested although the latter only compare complete discrete list values as opposed to matches within individual values as with a basic string match. More on attribute pattern matching.
