The prose which introduces the notion of 'context-determined declarations' suggests a mapping associated with each complex type which maps from element information items (or their expanded names), via the particles of the content model, to types. That's a convenient concept. But what is defined is only a subset of that mapping, omitting simple types and elements that match wildcards. There are technical reasons for the omissions, but they mean that the concept actually defined is not the concept described in the introductory prose and is not well captured by the term 'context-determined type'. Either a new term needs to be found, or the technical problems which led to the counter-intuitive aspects of the definition need to be solved in some other way. Perhaps 'locally declared type' ?
On 2008-09-26, the working group adopted a proposal to address this issue by adopting the suggestion given in the bug report, to replace 'context-determined declarations' with 'locally declared type'. The proposal (along with changes for other bugs) can be found at (member-only): http://www.w3.org/XML/Group/2004/06/xmlschema-1/structures.editorial0809.html
