Subject: Remember types in parser
X-Git-Tag: 0.4.0~4
X-Git-Url: https://git.ladys.computer/Shushe/commitdiff_plain/1c02c25ab49b46225f48d51ccc52648c20c82eaf?ds=inline;hp=56637a1e803cab7a53a1259d1fa4b84513a1c5b1

Remember types in parser

Rather than derive the types from the parser via a separate transform,
collect them when building the parser and remember them in a
`<html:dl>` which can be queried with X·Path.

This is a prerequisite to accessing this information at parse time,
but also a useful optimization in its own right.
