I suspect an error in the documentation page at https://github.com/antlr/stringtemplate4/blob/master/doc/null-vs-empty.md, in the table below the heading Multi-valued attribute values. In particular, the row for expression <x:{it | <it>}; null="y"> seems to inexplicably reference a in the column for x={null,b}, etc.
It look like this is simply a missing column separator. Pull request #160 to correct.
