Notes	The vast majority of current biodiversity data will be expected to not have a value in dwc:degreeofestablishment. This test could have value in determining 'quality' for a specific set of data quality needs/use cases.

not sure if we want to be consistent with https://dwc.tdwg.org/ or http://rs.tdwg.org/dwc/doc/ ?

Why does the note discuss leading or trailing whitespace? This is a test for EMPTY, therefore that text is not applicable.

This is one of several supplementary tests that, unlike core, almost certainly do not apply to flat Occurrence records. There are several tests like this that are very likely to apply to regional checklist data, probably attached to a Taxon record. That these tests are different in this sense needs at least to go into the notes, and probably elsewhere in a tag linked to higher level documentation about the assumptions of uses that the tests apply to.

In the absence of a clear use, this feels like it should be an issue rather than a validation.

[chicoreus]

This test is valuable, but applies poorly to the CORE use case as defined by TG3. Almost all occurrence data will (correctly) have no value in this term. It is very likely valuable for regional checklist data under invasive species use cases, but doesn't fit into CORE.

[chicoreus]

This test and #289 very likely need to consider other terms to assess whether a value should be present in the term. When a taxon is not introduced, dwc:pathway would be expected to be empty.

Non trivial work, and clear explication of the use case needed for both this and #289

[chicoreus]

Additional terms very likely needed as Consulted Information Elements.

Thanks @ymgan - minor but updated link.

[ArthurChapman]

@chicoreus - the use case is discussed in detail in the Groom et al. reference for this, Pathway, etc. There has been extensive discussion on these over the past few years and hence their addition to Darwin Core.

Removed reference to leading and trailing blanks.

As per my comments on #285, this would have to be Supplementary on the basis of returning a high percentage of EMPTY values (for now)?
