X3D Export and Import
Export and Import by Applications
The following applications are known to have X3D or VRML output capabilities. Additional entries are welcome.
The easiest way to convert VRML to X3D is to use a text editor: open the file and change the first line from #VRML 2.0 to #VRML 3.0 and Save As yourfile.x3dv! More details available here: X3D and VRML

There are three versions of text based scenegraph files which are commonly referred to as VRML
A. VRML, also referred to as VRML 1.0
B. VRML97, also referred to as VRML 2.0
C. Classic VRML encoding of an X3D scenegraph
To the majority of 3D content users and authors the distinctions between these dialects are unimportant and they are all thought of as VRML. Moreover, when an application supports VRML import or export it is usually not clear which of the A,B,C options are supported, but it can be determined from an inspection of the exported file. Files which are referred to a X3D for import and export are usually, in the ISO 19775 terminology. The forward compatibility is such that if you want to change a file from B to C you simply change the first line from #VRML V2.0 utf8 to #X3D V3.3 utf8.
D. XML Encoding of an X3D scenegraph.
In most cases when a user or feature support of an application says "X3D" it really means files of type D.
So the terms "X3D is VRML" and "VRML is X3D" can be explained as: Files of types C and D are completely interoperable and conform to the same scenegraph structure. The scene graphs are specified by the X3D standard, ISO 19975. X3D abstract scene graph (C and D) evolved some new nodes from VRML (B).
X3D is an evolving standard, currently at version 3.3. Backward compatibility among versions has been a principle of X3D development. Moreover, it a full-featured standard, with levels of support specified by profiles. So, for example, a file of type D "X3D" which conforms to version 3.3 of the standard, and conforming to the "Interchange" profile, can be losslessly converted to a file of type C, "VRML" at the same version/profile. Whether an application can read this as a VRML file depends on that application's support for the scenegraph features of X3D scenegraph at this version and profile.
VRML files of types B and C are syntactically equivalent, and the feature set of VRML97 is a subset of the feature set of X3D - ISO-19775. This combined with the backwards compatibility of X3D evolution, means we can convert B --> D files losslessly. The conversion of XML "D" files --> VRML "B" files will run into the feature issue you mentioned; how to support rich X3D features in VRML97, and resolution of the issue really depends on applications' development to support rich features, or to accomodate unknown features in a controlled way. This feature support mismatch problem is common among all evolving file formats, including applications' native file formats.
