// Call out to the individual language to classify the chunk of text around the

// Because the semantic tags may override the semantic ones (for example,
// "DateTime" might be syntactically an identifier, but semantically a struct
// name), we'll do a later merging step to get the final correct list of
// classifications. For tagging, normally the editor handles this. But as
// we're producing the list of Inlines ourselves, we have to handles this here.
