Error in specification of insert action "at" attribute

A "typo" of sorts was introduced into the last call working draft of 
XForms 1.1 regarding the evaluation context of the "at" attribute.
There was an overhaul of the whole section, and the error got in then.

If you read the description of the "at" attribute, it says it is evaluated 
using the inscope evaluation context.
It is supposed to say that it is evaluated using the nodeset binding for 
the evaluation context.

If you check the processing details of the insert action, specifically in 
step 4, you will see that it correctly describes the use of the nodeset 
binding for the evaluation context.

The more detailed description is the correct version, and here is the 
corroborating evidence:

1) The at attribute is specified as having no meaning when the nodeset 
binding is not expressed.
2) The delete action also has an at attribute, and it is evaluated based 
on the nodeset binding.
3) In XForms 1.0, the "at" attribute of insert was evaluated relative to 
the nodeset binding. In XForms 1.0, there was no default for "at", so if 
you wanted to insert at the end of the list you had to say at="last()". 
Such forms would stop working in 1.1.

We need to double-check the test suite to ensure that the interpretation 
of the "at" attribute is based on the detailed processing method, not the 
attribute overview.
