While working in CUS layer, I keep finding validate* methods that basically look like this:

public boolean validateWrite()
{
boolean ok = true;

ok = this.validateSomething() && ok;
ok = this.validateSomethingElse() && ok;
...
// johndoe 11.11.11 ->
ok = this.validateWrittenByJohnDoe();
<span style="color: #007f00;">// johndoe 11.11.11
