You should definitely be able to answer simple syntax questions like this
for yourself. The RM is complex to read, but the *syntax* sections should
be perfectly straightforward, and if you don't understand the BNF notation
that is used there, make the effort to learn and understand it (understanding
BNF is an absolutely essential piece of knowledge for any programmer). THe
relevant syntax rules can be found in Annex P, where they are gathered
together, or you can trivially find the right section in the RM with a
simple search (or using the index!):

4.6 Type Conversions

1   Explicit type conversions, both value conversions and view conversions,
are allowed between closely related types as defined below.  This clause also
defines rules for value and view conversions to a particular subtype of a
type, both explicit ones and those implicit in other constructs.

                                   Syntax

2   type_conversion ::=
        subtype_mark(expression)
      | subtype_mark(name)
