That's a very good reason, in particular for you.

It probably won't hurt if this is controllable. But there might be some existing applications (and tests) that expect single-quoted pseudo-attributes in XML declarations, and they would get problems if
doc.context[:attribute_quote] = :quote
changes that. So I think it would be better if it's something like
doc.context[:xml_declaration_quote] = :quote

Anyway, I don't have the time to prepare a patch, sorry. But maybe you can create a patch?

=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>
