Fields
EndFragment : string

Header : string
The string contains index references to other spots in the string, so we need placeholders so we can compute the offsets. The <<<<<<<_ strings are just placeholders. We'll back-patch them actual values afterwards. The string layout (<<<) also ensures that it can't appear in the body of the html because the < character must be escaped.
StartFragment : string
html comment to point the beginning of html fragment
_byteCount : char[]
Used to calculate characters byte count in UTF-8
