Feature Request: smart quote styles

Could we have an option like "xmlQuoteAttributes": "least_escape" that auto-detects the best quote style for the attribute based on how many of each quotation character is found in the value?

That way we can use quotation marks in values and still have it be readable.

bracketSameLine

None

printWidth

120

singleAttributePerLine

false

tabWidth

2

xmlWhitespaceSensitivity

ignore

xmlSelfClosingSpace

true

Input XML

<div class='row'>
  <div class='col-1' />
  <div class='col-9 ps-4' t-field='o.partner_id.name' />
  <div class='col-2' t-out="f'{o.amount:.2f}'" />
</div>

Current output XML

<div class='row'>
  <div class='col-1' />
  <div class='col-9 ps-4' t-field='o.partner_id.name' />
  <div class='col-2' t-out='f&apos;{o.amount:.2f}&apos;' />
</div>

Expected Desired output XML

<div class='row'>
  <div class='col-1' />
  <div class='col-9 ps-4' t-field='o.partner_id.name' />
  <div class='col-2' t-out="f'{o.amount:.2f}'" />
</div>

The issue names no files or tests. Start by tracing the XML attribute-formatting path and how formatter options are parsed, then determine how a least_escape choice should count quote characters in attribute values. Done means the option is supported and the supplied XML formats with the less-escaped quote style while existing options continue to work.
