FWIW, UI requirements for this kind of feature are not unique to LyX, XML
authoring tools typically have to deal with conditional text/profiling. For
instance, Oxygen XML and XMLmind have some UI for this (but it focuses on
showing the attributes that are used to filter out some content, i.e. it
shows the elements that the user can use to write their own logic to select
the content to output):

and https://www.xmlmind.com/xmleditor/_distrib/doc/profiling/index.html
