Help tips for structured Framemaker?

[Theresa de Valence]

Thanks to all for the pointers to building my own EDD using the manual 
"Developing Structured Applications" (Structure_Dev_Guide.pdf) from Adobe.

Where can I go and find out more about what the structured 
elements/attributes mean?

I've had no success with Adobe.com or the Framemaker 12 help pdf.

Specifically at the moment, I'm trying to find out how Frame decides 
when and how to apply "FirstIndentRelative" i.e. relative to what? In 
following the instructions, it seems to me all I did was input a value 
for a Paragraph Indent, but I have not told Frame any rules about WHEN 
to apply this command.

For those who don't have this exercise fresh in their memory ;-) there 
has been an Indent (0.3") added in all contexts to the Section element. 
The Title element has a (-0.3") FirstIndentRelative.

Is there some place where exists a list of elements & attributes which 
discusses what each means?

Thanks,
Theresa
