"iw_load_dcr" question

1)
The following two DCR files are equivalent:
[html]
+-------------------------------+---------------------------+
| "Traditional format" | "Arbitrary XML" format |
| ( x/y/trad.xml ) | ( z/arb.xml ) |
+-------------------------------+---------------------------+
|
|
| hi | hi|

+-------------------------------+---------------------------+



[/html]

iw_load_dcr loads DCR in the existing tpl. Does this DCR reside in the same "data" folder where primary DCR , for which this TPL is used to view, is kept ?

what does "x/y/trad.xml" mean in this example ? It looks like trad.xml is DCR, which is kept in y folder which is in x folder and thi x folder is kept in "data" folder. Where as z folder contains arb.xml DCR and "z" folder is kept in "data" folder.

It looks like "data' folder is considered as root folder while accessing a file. While accessing trad.xml, which is kept is "y" folder , we are mentioning x/y/trad.xml. While hierarchy is /templatedata/category/data-type/data/x/y/trad.xml.
Is this understanding correct or wrong ?

Can we create hierarchy of folders in "data" folder ? If yes, then how does DCR of this data-type access TPL for this data type ? Does not DCR need to be in the "data" folder, in order to access TPL ? If not, then can we create a hierarchy of folders in "presentation" folder also ?

I was trying to create DCR in "XML" format, but for whatever reason, DCR was getting created same as like "iwov" type. Why would that be ? Everything I need to do to create XML type DCR is to mention in templatiung.cfg that DCR created will be of XML type, right ? And not use root-container in the DCT ( I tried using root-container and without using root-container), but I am always getting DCR of iwov type

Thanks in advance for your replies.

Not quite. This is a slight error in the documentation - literally, the example in the docs and what you originally posted, is accurate - the two examples are equivalent - but in reality - an "xml" style DCT/DCR does contain a root-container, and thus the example provided is inaccurate.
Also, you cannot have DCRs of two different types ("iwov" and "xml") within the same data directory, as the type of the DCR is controlled by the type of the DCT - both how it is written, and how it is configured in

Yes - the 'data' folder is the root-folder for all DCRs of that particular data-type, and yes - you can (and often should) create a directory hierarchy within the data folder for at least these reasons:

If you do not follow all the requirements for an "xml" style DCT you may find that you end up with an "iwov" DCR instead, or you may find that the data you populate your DCT-form with does not show up when you then edit the same DCR after having saved it.
