Pattern is generally of the form +DD.MM.SS  (D=degrees, M=minutes, S=seconds)

Description of the pattern:
1) '+' or '-' required unless the value is 90.00.00 
	- if value is 90.00.00, then omit the '+' or '-'
	- '+' means North, '-' means South
2) A one-digit or two-digit number for degrees (range 0 to 89) - required 
3) A dot (the decimal between degrees and minutes) - required
4) A two-digit number for minutes (range 00 to 59) - required 
5) A dot (the decimal between minutes and seconds) - optional
6) A two-digit number for seconds (range 00 to 59) - optional
     - if there is a dot in step 5, then there must be a two-digit number for seconds
7) A dot (the decimal between seconds and parts of a second) - optional
8) Digits for parts of a second (can be any number of digits) - optional
     - if there is a dot in step 7, then there must be at least one digit after it

Examples:
+0.00.00
+00.00.00
90.00.00
90.00.00.0
-89.59.59
-89.59
-89.59.59.555


Pattern breakdown: (D=degrees, M=minutes, S=seconds)
(\+|\-)  (...see next line..)  |     90\.00\.00(\.0+)? <!-- choice of:  +(...DD.MM.SS pattern...) OR 90.00.00 -->
((\d|[0-8]\d)\.([0-5]\d))  (...see next line..) <!-- D (0-9), DD (00-89), and MM (00-59) ranges defined, followed by ... -->
((\.[0-5]\d\.\d+)   |   (\.[0-5]\d))?<!-- SS with decimal fractions of S *OR* SS without fractions of S *OR* no SS at all -->


The original pattern (just for insurance):
pattern value="(N|S)((\d|[0-8]\d)\.([0-5]\d)\.[0-5]\d(\.\d+)?)|90\.00\.00(\.0+)?"
