Access to XML checkpoint by name needed

In Files and Regions we work like this:

filetocompare = "C:\...\test.txt"
comparisonFileName = "TestFileName"

if not Files.Contains(comparisonFileName ) then
  call Files.Add(filetocompare, comparisonFileName , false)
  log.warning "Comparison file is generated newly"
else
  call Files.Items(comparisonFileName).Check filetocompare 
end if

We need something similar for XML checkpoints.

Currently you can check if it already exists with Contains. And you can create with CreateXML. But you cannot access the XML checkpoint by name (string).
