fx-insert into empty parent

The way fx-insert seems to be defined now, it is not possible to insert a first child element into an empty parent, e.g.:

<fx-control ref="instance('vars')/geography-term" value-prop="checked" update-event="input">
  <label for="geographyTerm"><pb-i18n key="form.geography">Geographie / Topographie</pb-i18n></label>
  <input id="geographyTerm" type="checkbox" class="widget"/>
  <fx-insert event="value-changed"
    if="context()/text()='true'"
    ref="instance()//textClass/keywords[@scheme='https://edh.ub.uni-heidelberg.de/edep/terms']/term"
    origin="instance('templates')/term[@ref='#geography']"></fx-insert>
</fx-control>

only works if @ref points to an existing term, so we need at least one as placeholder. However, the list of terms in keywords will initially be empty.

This can be done by using the 'context' attribute pointing to the parent and the 'ref' pointing to the child.

Example: https://jinntec.github.io/Fore/demo/insert2.html

to test:

delete all entries until list is empty
re-insert item

For your example try this:

<fx-insert event="value-changed" if="context()/text()='true'" context="instance()//textClass/keywords[@scheme='https://edh.ub.uni-heidelberg.de/edep/terms']" ref="term" origin="instance('templates')/term[@ref='#geography']"
