> In some circumstances it could be useful to dynamically fetch data from internal storage while loading initial content, especially for statements that need to comply with referential integrity.
> Essentially, we need to extend the feature introduced by SYNCOPE-1498 by allowing to populate variables after SQL query execution.
> For example, the following entry:
> {code}
> <fetch key="procDef" query="SELECT ID_ FROM ACT_RE_PROCDEF WHERE KEY_='userWorkflow'"/>
> {code}
> will define a {{procDef}} variable whose result is obtained by executing the given query. In the following lines its value can be referenced via {{${procDef}}}.
