Routine which creates a valid identifier string for the plain identifier string passed in and appends the fragments to the queryfragments specified. For example, the identifier will be surrounded by "[]" on sqlserver. If the specified rawIdentifier needs wrapping with e.g. [], the [ and ] characters are added as separate fragments to toAppendTo so no string concatenation has to take place. Use this method over CreateValidAlias if possible.

void AppendValidIdentifier(
	QueryFragments toAppendTo,
	string rawIdentifier
)

Sub AppendValidIdentifier ( 
	toAppendTo As QueryFragments,
	rawIdentifier As String
)
