  The hypothesis of limiting fragmentation (LF) or it is called otherwise
recently, as extended longitudinal scaling, is an interesting phenomena in high
energy multiparticle production process. This paper discusses about different
regions of phase space and their importance in hadron production, giving
special emphasis on the fragmentation region. Although it was conjectured as a
universal phenomenon in high energy physics, with the advent of higher
center-of-mass energies, it has become prudent to analyse and understand the
validity of such hypothesis in view of the increasing inelastic nucleon-nucleon
cross-section ($\sigma_{\rm in}$). In this work, we revisit the phenomenon of
limiting fragmentation for nucleus-nucleus (A+A) collisions in the
pseudorapidity distribution of charged particles at various energies. We use
energy dependent $\sigma_{\rm in}$ to transform the charged particle
pseudorapidity distributions ($dN^{\rm AA}_{ch}/d\eta$) into differential
cross-section per unit pseudorapidity ($d\sigma^{\rm AA}/d\eta$) of charged
particles and study the phenomenon of LF. We find that in $d\sigma^{\rm
AA}/d\eta$ LF seems to be violated at LHC energies while considering the energy
dependent $\sigma_{\rm in}$. We also perform a similar study using A
Multi-Phase Transport (AMPT) Model with string melting scenario and also find
that LF is violated at LHC energies.
