Bundled S-201 Aids to Navigation Information assets

These assets are bundled as embedded resources of the EncDotNet.S100.Specifications library and are exposed at runtime via:

Specification.OpenFeatureCatalogueAsync("S-201")
Specification.CreateFeatureCatalogueSource("S-201")
Specification.CreatePortrayalCatalogueSource("S-201")

Edition

S-201 Edition 2.0.0, Apr–May 2025 (aligned with S-100 Edition 5.2.0).

Component	Identification
Feature Catalogue	`S100FC:productId="S-201"`, `versionNumber="2.0.0"`, `versionDate="2025-05-19"`
Portrayal Catalogue	`portrayalCatalog productId="S-201" version="1.0"` (manifest version is distinct from spec edition)
Top-level rule	`main_PaperChart.xsl` (`ruleType="TopLevelTemplate"`)

Provenance

Sourced from the IALA-IGO upstream repository:

Repository: https://github.com/IALA-IGO/S-201_AtoN-Information
Commit: 7ddfe8145812141fb8ca413107254f42febd893e
Branch: main (fetched 2025-05)

Files inside fc/ and pc/{Rules,Symbols,ColorProfiles,Fonts}/ are byte-identical to upstream after the renaming described below. Do not edit them in place; if upstream needs adapting for this codebase's XSLT engine, follow the S-411 pattern and add a separate Adapter/main.xsl that wraps the upstream catalogue.

Rename mapping (upstream → bundled)

The upstream zip wraps everything in an extra 7. S-201 Portrayal Catalogue - Annex D/ directory and uses documentation-style numbered prefixes on top-level files. Both inconveniences are stripped on bundling so the layout matches every other product in this repository:

Upstream path	Bundled path
`6. S-201 Feature Catalogue - Annex C2.xml`	`fc/FeatureCatalogue.xml`
`7. S-201 Portrayal Catalogue - Annex D.zip` (root)	`pc/` (contents only — wrapper folder stripped)
`pc/.../portrayal_catalogue.xml`	`pc/portrayal_catalogue.xml`
`pc/.../Rules/*.xsl`	`pc/Rules/*.xsl`
`pc/.../Symbols/*.svg`	`pc/Symbols/*.svg`
`pc/.../ColorProfiles/{colorProfile.xml, svgStyle.css}`	`pc/ColorProfiles/{colorProfile.xml, svgStyle.css}`
`pc/.../Fonts/*.ttf`	`pc/Fonts/*.ttf`

After flattening: 1 FC, 1 PC manifest, 65 XSLT rules, 237 SVG symbols, 1 ColorProfile + 1 svgStyle.css, 4 fonts (Droid Sans / Open Sans).

The S-201 PC ships a single Day-only color profile; no Dusk/Night variants are provided upstream.
