Details:

mapping package version 1.4.1

This concerns documentation for the Attributes property/value pair.

In the first example, I defined Attributes to include:
{"BoundingBox","X","Y","GEOID20"}  The first three are in the .shp file but
not in the .dbf file.  The example fails to read "GEOID20" from the .dbf
file.

In the second example, I defined Attributes to include only "GEOID20" and
everything worked fine.


octave:381> attr = {"BoundingBox","X","Y","GEOID20"};
octave:382> bl =
shaperead(BLNAME,"BoundingBox",[lon,lat],"Attributes",attr,"Recordnumbers",[1:1000:150000])
shaperead: file /home/maier/bob/IRC/CENSUS/tl_2021_04_tabblock20.dbf couldn't
be read;
           no attributes appended
bl =

  10x1 struct array containing the fields:

    Geometry
    BoundingBox
    X
    Y

octave:383> 
octave:383> attr = {"GEOID20"};
octave:384> bl =
shaperead(BLNAME,"BoundingBox",[lon,lat],"Attributes",attr,"Recordnumbers",[1:1000:150000])
bl =

  10x1 struct array containing the fields:

    Geometry
    BoundingBox
    X
    Y
    GEOID20

octave:385>


The Attributes cell list evidently should NOT include any attributes included
in the .shp file, such as "BoundingBox".  Including them will cause dbfread to
fail.   

Perhaps this is simply a matter of documentation?  

Great package!  Thank you.
