SAX API uses unsigned std::size_t but -1 if element size is not known;

[steven-varga]

In the SAX API std::size_t defines the size, however in the documentation -1 a different type signals unknown size. Did I overlook something?

What is the exact question? Indeed, if the size is known during parsing, a size can be passed to the start_array() or start_object() functions. If it is unknown, std::size_t(-1) is passed (just similar to std::basic_string::npos.

Thanks for explaining. I was not aware of this technique and was surprised to see an unexpected high value with std::size_t when took your library for a test run. Sorry for the noise!
