Hello,

I’m currently studying the FAST 1.2 extension proposal, and have the following questions:

1.) The type definition - according to the proposal document - “accepts the normal type elements without the name attribute”. Is it correct, that only the name attribute is missing in the definition? For example, can I specify the presence or the id attribute also in the definition section?

e.g. can I define the type for the decimal field

like this?

and if I use the type definition MDEntryPxType in the template, what happens with the presence attribute?

The last occurence of the presence attribute is located according to the xml-hierarchy in the type definition of MDEntryPxType. Does it mean, that the mandatory presence attribute assigned directly to the field MDEntryPx will be ignored?

2.) Another question: Is the following usage of the field definition correct (using the same type definition with different fast operator)?

in template t1:

in template t2:

in template t3:

Thanks,
