I'd like to build a workflow that creates a list of points for each alignment chain from an XML file. Is this possible? The points would be at each end of the alignment and a specified equidistant along the alignment. Is this possible?
Question
Can I read an xml containing horizontal geometry for an alignment chain (in N,E) and have it write out a list of points along the alignment(s) (in lat,long)?

Yes. Use Reprojector, PROJReprojector, CSMAPReprojector, or any other reprojector you need to get your data to Lat/Long, then use the DistanceMarker transformer from the FME Hub.
Then just create the attributes you need (with @XValue, @YValue).

Short answer is https://www.safe.com/training/recorded/
Long answer: figure out what kind of xml you have, use the apropiate reader, get the geometry (GeometryReplacer maybe), create the points along your line with DistanceMarker, reproject to a lat/long projection, use attribute creator to create Lat and Long attributes from point coordinates. So: XML Reader - > DistanceMarker - > Reprojector - > AttributeCreator - > Writer of your choice
