[Pkg-rust-maintainers] Bug#1093508: please upgrade to v0.27

[Peter Green]

Looking at the package descriptions I think html5ever, xml5ever and markup5ever should probablly be updated as a group.

So either

html5ever 0.27, markup5ever 0.12, xml5ever 0.18

html5ever 0.28, markup5ever 0.13, xml5ever 0.19

html5ever 0.29, markup5ever 0.14, xml5ever 0.20

Looking at the rdeps

rust-ammonia - rust team package, latest upstream uses html5ever 0.27, debian is up to date

rust-html2md - latest upstream uses html5ever 0.27 and is not semver-breaking

rust-html2pango - upsteam has not yet updated

rust-html2text - latest upstream uses html5ever 0.29, 0.12 upstream uses 0.27 both are semver breaking. Will probablly investigate backporting.

rust-librsvg - latest upstream uses xml5ever 0.18, debian is up to date

rust-markup5ever-rcdom - test crate for markup5ever.

rust-scraper - latest upstream uses html5ever 0.29, upstream 0.20 uses html5ever 0.27, both are semver breaking but no rdeps

rust-select - upstream is still on 0.26

rust-upstream-ontologist - upstream does not specify an upper limit

Based on these, it looks like html5ever 0.27, markup5ever 0.12, xml5ever 0.18 wins,
I will start preparing the update and see if I run into any problems.
