BaseContainers are ignored on XTCE import

[JBBanks2]

Description

It seems that BaseContainer's are ignored with XTCE import.

Steps to Reproduce

1. Attempt to import the XTCE provided below
2. Check the "Parents and Children" tables

Example XTCE (click to expand)

```xml ```

Expected Behavior Foo should extend Bar

Observed Behavior Foo does not extend Bar

Additional Info

Also, if you export Foo and Bar after importing them, the BaseContainer node is no-longer present in the exported XTCE

Could you provide an example of what you expect this table to look like after an import?

Hi bawi235!

I'd expect to see Foo be a child of Bar. Either that or see the fields of Bar prepended to Foo's entry list.

From XTCE Green Book section 4.3.4.9:

A container may extend another container in an object-oriented manner. The child container receives the parent’s EntryList, and that EntryList is exactly prefixed to the front of the child’s EntryList. 

Right now, I don't see an indication of any relationship between Foo (child) and Bar (parent) in the CCDD UI.

Will be adding an updated version of CCDDv2 later this week that helps address a problem I am encountering with XTCE imports. Will post an update here when it is available.

Version 2.0.23 is out. I was able to import the attached file to achieve, what I think, you are trying to do. Keep in mind that CCDD supports a limited sort of XTCE, tailored for use by the display group who work(ed) the Habitat project. The only guarantee is that CCDD can import its own exported XTCE files. XTCE that's formatted differently won't work. XTCE "features" not already covered in CCDD's XTCE parser will be ignored (or maybe cause odd behavior).
