[CWB] Structural Attributes

[Hardie, Andrew]

Very nice tabulation Serge, but FYI - and in my customary spirit of nitpicking - can I point at this para from Evert & Hardie (2011:8)...

>>
The third key aspect to how CWB works is the query language used within CQP, which we 
call the *CQP Query Language* or *CQP-syntax* for short. This language is sometimes referred 
to in the literature as *Corpus Query Language* or *CQL* (for example, in papers related to the 
SketchEngine software). We do not use this term, however, and we strongly recommend 
against its use by others, because "CQL" has been in use for a long time as the name of a 
non-corpus query language standard promulgated by the US Library of Congress, as well as 
a label for the underlying query language of the SARA/Xaira software.
This latter "CQL" is XML-based and therefore incompatible with CQP-syntax.

You can also put the year constraint directly into the word constraints:

	[word=".*ion" & _.text_year="1900"] []{3,5} [pos="V.*"]

See line 141 of CQL syntax reference document at:

Best,
