Now, the root node of a document is always a document node. It will often have only one child node which corresponds to the grammar's start symbol, but not always. Currently, it may have more than one child if there are ubiquitous tokens such as comments at the beginning of the document. In the future, it will also be possible be possible to have multiple for the document to have multiple children if the document is partially parsed.
