#
# RELAX NG schema for XRC files.
#
# See http://docs.wxwidgets.org/trunk/overview_xrcformat.html for freeform
# description of the format.
#
#
#  Extending the grammar
# -----------------------
#
# The grammar defined below validates all builtin <object> classes. Because the
# XRC format is extensible, it allows any content in <object> nodes that have
# non-builtin class.
#
# This can be customized by overriding the 'customClasses' rule in the grammar
# when including it from another custom grammar file.
#
# For example, if you wish to validate that only wx's builtin classes are used,
# you can disallow any custom <object>s (see xrc_schema_builtin_only.rnc):
#
#     include "xrc_schema.rnc" {
#         customClasses = notAllowed
#     }
#
# You can also add validation for custom classes:
#
#     include "xrc_schema.rnc" {
#         customClasses = myExtensionClasses
#     }
#
#     myExtensionClasses = (MyFoo | MyBar | ...)
#     MyFoo =
#         element object {
#             attribute class { "MyFoo" },
#             stdObjectNodeAttributes,
#             ...
#         }
#     ...
#

        # both.  Additionally, even though the attribute is optional in the
        # spec, we require it here; in other words, the schema cannot be used
        # to validate XRC files from previous millennium.

# IMPLEMENTATION NOTES:
#
# The guiding principle for writing this schema is to validate as much as we
# possible can, but without introducing false negatives; it is not acceptable
# to fail validation of a valid (per the human-readable XRC spec) XRC file.
#
# Unfortunately, there are some noteworthy complications when describing the
# XRC format with a formal schema. Working around them results in uglier and
# overly permissive schema:
#
#
# (1) The biggest issue is with the 'platform' attribute, which may be used on
# _any_ node in an XRC document. There's no way to specify "universal"
# attributes that can be placed anywhere in RELAX NG, so we must add the
# attribute everywhere. The 'platform' grammar rule is used for this and it has
# an alias, '_', for reduced verbosity. Typical use:
#
#       element size   {_, t_size }? &
#
#
# (2) The other 'platform'-related issue is that it messes up cardinality of
# properties elements. Properties can only be specified once, so the two forms
# for describing properties would be
#
#       1. element size {_, t_size }?   # optional property
#       2. element size {_, t_size }    # required property
#
# (Fortunately, all XRC properties are optional, se the second case is a
# non-issue and can be safely ignored. It is nevertheless briefly mentioned
# below for explanatory purposes.)
#
# But this is problematic with 'platform', because it's reasonable (and,
# indeed, done in the wild) to set properties differently for different
# platforms:
#
#       <object class="wxMenuItem" name="menu_new_from_pot">
#           <label platform="win">New catalog from POT file...</label>
#           <label platform="unix|mac">New Catalog from POT File...</label>
#       </object>
#
# But we now have the 'label' property _twice_ and validation fails. The
# simplest fix is to change the cardinality of properties to allow this [A]:
#
#       1. element size {_, t_size }*    # optional property (0 or more times)
#       2. element size {_, t_size }+    # required property (at least once)
#
# Of course, this is too lax and allows invalid (but gracefully handled by
# wxXmlResource) markup like this:
#
#       <object class="wxMenuItem" name="menu_new_from_pot">
#           <label>Something</label>
#           <label>Else</label>
#       </object>
#
# We could make this better by splitting the property declaration into two, one
# for the case with 'platform' and one for without [B]:
#
#       (element size { t_size } | element size { attribute platform{string}, t_size }+)
#
# But this is verbose and unreadable with the amount of properties present in
# the schema. Instead, we use the more-forbidding version and annotate
# properties with 'p' annotation (for "property") to mark these uses of * as
# special and enable post-processing of the schema.
#
# The value of the annotation is normally just "o" (for "optional" -- remember
# that there are no required properties) to indicate optional properties.
#
# Since we have the annotation anyway, we take advantage of it to indicate
# properties that are strictly speaking optional, but should almost always be
# specified, even though they don't _have_ to be. A typical example would be
# wxStaticText's label: it very rarely makes sense to omit it, but usually
# doesn't. Such properties are indicated with the "important" value of the
# annotation:
#
#       [xrc:p="o"] element checked { t_bool }*        # optional
#       [xrc:p="important"] element label { t_text }*  # should be provided
#
# This makes it possible to implement tools that translate this schema into a
# variant that uses [B].
