The current behavior is dangerous because I might write code, test it, see that it's working, put it into production and have it run correctly for two weeks at which points somebody throws a document that's formed in a slightly different way at it and it processes it incorrectly. Consequently a trade doesn't get executed that should be, or vice versa, or it gets executed at the wrong price. A laser scalpel cuts along the wrong coordinates. A nuclear reactor fails to shut down. Most cases would be less catastrophic than this, but you get the idea.
If I have designed my code to miss handling an important case, then it should immediately notify someone that it's entered an unexpected state that it cannot properly handle. I would prefer to make this particular exception a checked exception so that programmers would be forced to consider the possibility of mixed content and how they'll handle it if it arrives. But regardless of whether the exception is checked or unchecked, silent failure is not an option. The method either succeeds or it tells somebody that it failed.
