Ordering or giving ranks to rows in a data set with condition.

[mesujit]

I want to give the Order/ranking to my data set TAXDEPT (output in Rank col.) as shown below using PROC SQL. 

My source data set is in below form now:

SiteID is already in sorted form.

where ever SiteTax == allTax, i have to give ranks like 1,2,3,...

where ever SiteTax != allTax, i have to give sub-ranks like 3.1, 3.2, ....4.1, 4.2, ....

like for SiteID 211 below i need like; 4.1, 4.2, 4.3

TAXDEPT:

Country	SiteID	SiteTax	Rank
All Country	allSite	allTax	1
Austria	allSite	allTax	2
Austria	32	allTax	3
Austria	32	a1	3.1
Austria	211	allTax	4
Austria	211	a2	4.1
Austria	211	a3	4.2
Austria	211	a9	4.3
Austria	330	allTax	5
Austria	330	b2	5.1
Austria	330	b3	5.2
Austria	330	b1	5.3
Austria	330	c2	5.4
Canada	allSite	allTax	6
Canada	211	allTax	7
Canada	211	q1	7.1
Canada	211	q3	7.2
Canada	211	q2	7.3
Canada	579	allTax	8
Canada	579		8.1
Canada	579		8.2
Canada	579		8.3
Canada	666	allTax	9
