They are pretty much for the plugins only
Yes, escape could very well be for plugins only. I was quite clear about what problem I was trying to fix.
and the only use I've found for them so far is outputting complex litteral strings which contain aXML/Perl...
Or just plain XML. Without these fixes, I wouldn't be able to use aXML for two of the three XML formats I deal with, and it would be very fragile for those with which I could use aXML.
Re^8: Thanks to Ikegami, Chromatic & Corion could be seen as a continuation of this post.
