Issue #9367 has been updated by Kouhei Sutou.


* `include StringQuotes` after `private` is meaningless. Please put it the top of class definition.
* It seems that `strip_quotes` is needless for `adjust_prologue_quotes`. Can we just remove `.inspect` from `adjust_prologue_quotes XXX.inspect`? If we can do it, `adjust_prologue_quotes` isn't good name. `quote` or something will be good name.
* Please don't omit parenthesis for method call in `#{...}`.
* Please don't set `DocDecl` as `NotationDecl`'s parent. (It was mentioned at #9367-9.) How about calling `context` method instead of getting context from `@parent` in `adjust_prologue_quotes`? It seems that `adjust_prologue_quotes` is too depends on internal implementation.

(Sorry for my many comments...)

Bug #9367: REXML::XmlDecl doesn't use user specified quotes

=begin
REXML uses double quotes for quoting attributes if :attribute_quote is specified as document's context like below:

 doc = REXML::Document.new
 doc.context[:attribute_quote] = :quote

This looks working well on all elements but has no effect for xml declaration (i.e. <?xml version= ... ?>) if it exists.

Even if I specify (({doc.context[:attribute_quote] = :quote})), I will get this:

 <?xml version='1.0' encoding='UTF-8' standalone='true'?>
 <root attr1="value1">
   <child attr2="value2"/>
   <child attr3="value3"/>
 </root>

The expected result is:

 <?xml version="1.0" encoding="UTF-8" standalone="true"?>
 <root attr1="value1">
   <child attr2="value2"/>
   <child attr3="value3"/>
 </root>
