Filesystems Supported by Solaris

Could someone please tell me which filesystems are supported by Solaris?

I am specifically interested in ext2, ext3, and XFS.

Is XFS included in a standard Solaris distro?

Are ext2 and ext3 only supported in Read-Only using lxrun?

Thanks.

don't think that any of that are supported by the solaris-kernel.
solaris FSes are something like:
UFS (system FS)
VxFS
SAM-FS
QFS
PC-FS (Fat16)
NFS
CXFS
HSFS
