1. There is no possibility in XSD to make complex keys parent[@id]/sub[@id]. Therefore, 
the schema requires all "layout" and "configuration" in various installation to have 
different ids. Since the current microseconds are used to generate IDs, it should not be
a problem.

2. The complex element consisting of unbounded amount of xs:any elements can't
be restricted to the certain list of arbitrary elements (it works with 
attributes). Therefore, "ComplexData" contains declaration of all elements 
which can appear in any ASEC data types.

3. There is consideration in "get" script, what there is not "*Data" tags inside
of the datarecord.
