Description:
------------
A lot of the file/stream accessing functions have a context parameter.

In contrast, SimpleXMLElement::__construct() and simplexml_load_file() do not.

Both are able to use other contexts though, since you can change the context in use using libxml_set_streams_context(). 

The problem with that is, that future requests using any of the other xml extensions are affected as well by using the function mentioned above. 

In the interest of a consistent interface and a minimized risk to break things, it would be nice to see a context parameter for the SimpleXMLElement::__construct() and simplexml_load_file().

Furthermore a hint in the manual entries for both functions to libxml_set_streams_context() or contexts in general would be good.

I just spend a number of hours debugging my code, and the error turned out to be a missing context reset in a class from somebody else... :(

Done[1].

Wrt. the feature request, I suggest to pursue the RFC process[2];
otherwise it's likely that this ticket will be unaddressed for
another ten years.  For the time being, I suspend it.
