How should multiline marks work? Does it mean that in mark you can specify several functions?

First type:
If one of functions was matched with any string than the mark will be connected. That means that each regexp function must have the same set of groups so the pattern of problem will be correct for all of functions.

Second type:
When one line is matched with first function than the next line should be matched with second function and so one for mark to be connected with unknown report. This is more strict than current marks.

Third type:
Match all functions with all of lines and when I find all lines for each function then I will connect the mark.

Fourth type:
Like in 3d type I'm searching all matches in all lines for all functions. But like for unsafes I can introduce "similarity". And connect mark when at least one match was found (similarity > 0).

No, there will be a single function, namely regular expression, but it can contains new lines. At the moment pattern "a\nb" doesn't match failure description:

a
b
