What is the purpose of scripting_enabled and iframe_srcdoc in swc_html_parser::parser::ParserConfig?

[phoenix-ru]

I am working on a native Vue compiler (unofficial), and so far experience with swc_ecma_parser and swc_ecma_codegen in Rust has been amazing. I want to use swc_html_parser instead of a naive nom parser or html5ever.

Could you please advise, what is the point of ParserConfig in relation to SWC and parsing HTML?
https://rustdoc.swc.rs/swc_html_parser/parser/struct.ParserConfig.html

pub struct ParserConfig {
    pub scripting_enabled: bool,
    pub iframe_srcdoc: bool,
}

There unfortunately is no documentation for these two fields, and I am not sure of their impact. Does this have anything to do with how <script> tags are parsed?

I think it's for parity with the specification, but let's check again.

@phoenix-ru Sorry for delay, it is for parsing the srcdoc attribute of the iframe tag https://developer.mozilla.org/en-US/docs/Web/API/HTMLIFrameElement/srcdoc, yeah it is a part of HTML spec
