GMLLoader
The GMLLoader parses the XML-formatted response from the
the OGC-standardized GML (Geographic Markup Language) file format into a standard geospatial feature table.
Note that the GML standard is very ambitious and full support of the format is out of scope.
| Loader | Characteristic |

| File Extension | .gml |

| Data Format | Data structure |
| Decoder Type | Synchronous |

Usage
import {GMLLoader} from '@loaders.gl/wms';
import {load} from '@loaders.gl/core';
// Form a GML request
const url = `${WFS_SERVICE_URL}?REQUEST=GetFeature&...`;
const data = await load(url, GMLLoader, options);
Parsed Data Format
The GMLLoader only supports parsing the standard geospatial subset of features (points, multipoints, lines, linestrings, polygons and multipolygons), on a "best effort" basis. Because of this, the GMLLoader is treated as a geospatial loader and can return GeoJSON style output.
