"start" value for translation to kindle not working

[GoogleCodeExporter]

What steps will reproduce the problem?
1. statement in content.opf:     <reference 
href="Text/ROC_Alizant_split_000.htm#start" title="Beginning" type="start" />  
2. Run Sigil validator
3. get error msg: The <reference> element's "type" attribute has value "start" 
which is not an OPF-specified value. Either use  predefined type or start your 
type with "other"

What is the expected output? What do you see instead?

This is a fairly common recommendation for setting the "Beginning" start point 
for a mobi/Kindle file. It seems to work sometimes, but not consistently. 
Whether or not the translation works, I still get the above error from the 
Sigil validator.

What version of the product are you using? On what operating system?

Sigil, ver 0.5.3, current Kindle previewer for the mobi translation. Windows7, 
up do date.

And it creates an INVALID epub. FlightCrew is a strict epub validator. 
Recommendations for adding non-standard attributes so and epub converts to a 
proprietary format using a proprietary converter are still not valid.

Oh...I have been properly chastised. :D I need to convert to several formats 
for readers. Sorry. No room for elitism. :D

Actually, going against several of the "experts" on epub and designating it as 
type "text" rather than "start" makes both Sigil's Epub validator and Kindle 
happy. Solving one solved the other. ;D

Problem solved.

Thanks anyway.

Have a nice day.
