Chad,

marking up the datasets from my site, I find the following units that
are undefined in eml-unitDictionary.

1.  Year (awaits resolution of date, perhaps) e.g.  1999.  Year in which
sampling occurred.

2.  Date (awaiting resolution?)

3.  metersPerGram.  could be of type massSpecificLength.  refers to
fungal hyphae in grams of soil.  

4.  cubicMicrometersPerGram.  massSpecificVolume?.  refers to bacterial
volume in grams of soil.

5.  pH. (negative log of the hydronium ion concentration of a solution,
where concentration is presumably molesPerLiter).

6.  gramsPerHectarePerDay.  multiplierToSI:  "0.0000000000011574"

7.  numberPerGram.  Bacterial counts.

8.  gramsPerSquareMeter.  multiplierToSI:  "0.001"

I think 6-8 should certainly be added.  I'm hopeful on the others, so I
don't have to custom define.  I have lots of units in the form
gramsPerGram that I don't know what to do with.  

Note:  I think there's some inconsistency in unitDictionary names
regarding meterSquared vs. squareMeter.  Maybe not critical.

Tim.
