Used by: This entry is used directly by one other data structure in this standard, a MSG called
MSG_RTCM_Corrections <ASN> <XML>.   In addition, this item may be used by data structures in
other ITS standards.
Remarks: In order to fully support the use of networked transport of RTCM corrections (so-called Ntrip
systems), the enumerated list of protocol types provides for all the common types outlined in RTCM
Standard 10410.0, Appendix B.  It is anticipated that revisions 3.x and 2.3 will predominate in practice. 
7.69 Data Element: DE_Short Latitude
Use: A shorted value of latitude representing the lower 16 bits of a 32 bit value.   Taken together with the
Long Latitude data element, a complete value of latitude can be obtained which is identical in value domain
to the std ITS latitude with an LSB of one 1/8th micro degree.  The latitude is the position of the center of
the vehicle, expressed in 1/8th micro degrees and based on the WGS-84 coordinate system, represented in a
4 byte value.
ASN.1 Representation:
ShortLatitude ::= INTEGER (0..65535) -- lower 16 bits of a 32 bit Latitude
XML Representation:
<xs:simpleType name="ShortLatitude" >

In addition, this item may be used by data structures in other ITS standards.
