Also an important aspect, I pointed out that the banana examples in O&M were my lifelines..

Ok, looks like the ball stopped bouncing here.
Do we go forward with the instance document from a legend/story ? Do we have agreement from people who commited to those use cases ?
I would certainly be interested in taking a real map unit description and putting it in GeoSciML, but I see it as a documentation/guidelines kind of artifact. Having several people do the encoding independently for several different descriptions, then 'harmonizing' the results for each description, and putting the description, the GeoSciML and describing the decisions made in a document would be very useful to have for teaching.
We just need to collect some descriptions to use.
for example, the one used by NADM:
>From Harald Drewes. 1998, Geologic map of the Bartlett Mountain Quadrangle, Pima and Santa Cruz counties, Arizona, USGS I-2624. Lat 31 deg 22'30" to 31 deg 30', long 111 deg 15' to 111 deg 22'30". Scale 1:24,000 (1 inch = 2,000 feet). The text of the legend item:
Dacitic Vent Breccia (Miocene) -Light-medium-gray, finely porphyritic dacitic rock containing inclusions of Jurassic or Proterozoic granite and Jurassic rhyolite (welded tuff?) as much as 20 m in diameter. The subcircular outcrop mass of breccia probably is a volcanic vent or throat. A halo of strongly saussuritized rock 0.3 -0.5 km wide (delineated on map) surrounds this vent. The dacitic matrix consists of phenocrysts (25-35%, as much as 2 mm in length) set in a cryptocrystalline granular groundmass. Phenocrysts included albitized(?) plagioclase (12-18%), chloritized biotite (2-5%), uralized amphibole (2-10%), magnetite (trace to 2%), and apatite (trace). Quartz is present as a secondary mineral, filing vugs.
