> There are certain pieces of a FlowFile that are not attributes (entryDate, lineageDate, and fileSize); howwver, the output from a logAttribute processor identifies them as FlowFile attributes.  These items should be labeled as FlowFile properties.
> --------------------------------------------------
> Standard FlowFile Attributes
> Key: 'entryDate'
>         Value: 'Tue Nov 10 09:02:01 EST 2015'
> Key: 'lineageStartDate'
>         Value: 'Tue Nov 10 09:02:01 EST 2015'
> Key: 'fileSize'
>         Value: '10240'
> FlowFile Attribute Map Content
> Key: 'divideby3'
>         Value: '-7'
> Key: 'divideby5'
> .....
> ----------------------------------------------------------
> Need to change the output wording:
> "Standard FlowFile Attributes" should be "Standard FlowFile Properties"
> I also think uuid should be included under this section.
> We want to avoid confusion for the users.  All Attributes are stored as strings.  Properties are not attributes and are not stored as strings. That distinction directly correlates to how the expression language can interact with these values.
