Field attribute is not consistent with field data attribute?

[Carl19 <i....@gmail.com>]

A lucene field has some attributes (eg. storeTermVector ...), when 
a document is added these attributes are updated, so how these
fields attributes can represent all field datas attributes? 

For example, when add doc1 (field a's storeTermVector is false), 
doc2(field A's storeTermVector is false), doc3(field A's storeTermVector 
is true), the field A's attribute storeTermVector will be true, and 
FieldsReader will read back these 3 docs with field A's storeTermVector
is true, but actually there is no term vector stored for field A of doc1, 
doc2.

some properties are specific to the field across the entire index, 
regardless of how many docs use them -- fieldNorms for example exist for 
all docs as soon as one doc has an instance of that field that does not 
omitNorms.  Off the top of my head, i can't remember if storeTermVector 
works like that ... i seem to recall some fairly straight forward 
documentation about which properties are per field name, and which are per 
field instance, but i'm not finding it at the moment.

Does anyone know if/where this is documented?  is it only in LIA?
