  No. It just mean that the xmlSetProp API has that characteristic.

  If you use 1.8.17 I just don't want to hear about bug reports,
it's purely a compatibility library for teh legacy Gnome 1.x platform
and I have asked everybody else to use libxml2 for a couple of years at
least. Anyway I doubt XML::LibXML uses it.
  I do not control PHP and Perl bindings. I have no idea what they actually
do at the library interface, the only bindings I accept bug reports for is
the python one.
  Again the behaviour of xmlSetProp() may be strange, but I won't change
it. In the worse case if you prove me it makes things really hard I may
create a new API, but so far I am not convinced. I will not break the
existing applications based on your existing test case. More fundamentally
you seems to believe that attribute and text node content should be expected
to behave in the same way while this is definitely not true as dictated
by the XML specification, attribute values have restrictions, and are
modified by the parser before being passed to the application. 
  It's perfectly possible with the current API to change the attribute
to a given substring without using xmlSetProp(). An attribute has children
which are usually a single text node, possibly an alternance of text node
and entities reference, you can modify directly the content of the text
node children if the API behaviour doesn't suit you.
